>> From the Library of Congress in Washington, D.C. [ Pause ] >> Michael Turpin: Well, good evening, everyone. >> Good evening. >> Michael Turpin: My name is Mike Turpin, and I know you. Good to see you again. I'm a Recording Engineer here in the Music Division. Those of you who regularly attend these concerts and pre-concert lectures are used to seeing me on the other side of the microphone, but now that we're well into our 90th season I thought it'd be a good idea to look back at some of the legendary performances that have taken place on the Coolidge stage, many of which I've had the pleasure of recording. Now contrary to what some of my colleagues might tell you, I have not been here 90 years. [laughter] I have been here long enough, though, to have witnessed some significant changes in both the programming that we offer, as well as the technology used to record and preserve it, so I'll be talking about that over the next hour. First, let me thank a few people. My capable associate, Jay Kinloch, back at the controls there, Jay has been working with me for several years now and doing a great job. Also, our friends in the ITS Multimedia Group, who are recording this for the web. I guess it'll show up there sooner or later. And also want to thank my colleagues in the Concert Office, who make it fun to come to work every day, well, most days. [laughter] Now some of you know the history of the Coolidge Auditorium, that it opened in the fall of 1925, thanks to the diligent efforts of Elizabeth Sprague Coolidge, a woman who was ahead of her time in many ways. A musician, herself, she had a passion for chamber music and wanted to share it with as many people as possible. Having an auditorium built specifically for chamber music, housed and maintained by a Government institution was a pretty unusual idea in 1924, but she made the proposal to then Librarian of Congress, Herbert Putnam, and Music Division Chief, Carl Engel [Assumed Spelling]. It literally took an act of Congress to make it happen. The idea grew out of successful chamber music concerts and festivals she organized in Pittsfield, Massachusetts. What you might not know is that Mrs. Coolidge had radio equipment installed in the Auditorium right from the beginning, even though radio was still a fledgling medium at the time. Some of those first concerts were carried by the Navy's Broadcasting Service in Arlington. Unfortunately, there are no known recordings of those broadcasts, but by the mid-1930s NBC was bringing chamber music to the homes of people who might not have otherwise heard it. Here is a rare recording of Mrs. Coolidge speaking about her idea to bring chamber music to the masses at her 80th birthday concert in 1944, and that is Harold Spevak [Assumed Spelling] with her. >> After seven years in Pittsfield the chamber music festivals had grown to such proportions and seemed to me so important that I decided to perpetuate them by placing them under institutional management. Still another chance suggestion then led me to consider the Library of Congress as the most desirable and personal and permanent administrator of my cherished project. [Inaudible] and the Librarian, Mr. Herbert Putnam, proved deeply sympathetic and enormously helpful in bringing this about, and I was not only very glad to share an increasingly heavy responsibility, but also welcomed the opportunity to establish in the Government a little wedge of authority in matters of art. I think I was even kindly accused of a little wrangling and perhaps justly for I could wish for music the same Governmental protection that is given to hygiene, education or public welfare. How wonderful if we could have in the Cabinet a Secretary of Fine Arts. I feel that I the course of 26 years my concerts have developed and guided my career as much as I have guided them. One idea has evolved another. One event has grown into another. I have followed their direction into paths and faced entirely unforeseen, until today I find myself in your midst at this festival feeling the radiation of friendship and beauty, which chamber music broadcasts. As I feel returned messages augmented a thousand fold which center in this little Auditorium in the Library of Congress. >> Michael Turpin: And speaking of Mrs. Coolidge I want to make sure you all know about the great exhibit on her life and legacy, which you can view over in the lobby of the Performing Arts Reading Room in the Madison Building, right across the street. It will be up until January 23rd, so you still have some time to check that out. I encourage you to do so, it's a great exhibit. In 1935 the Library received another generous gift, Gertrude Clarke Whittall donated her collection of Stradivarius instruments that live in this room named after her, but they came with a condition that they be played regularly and not just sit in the display cases. So every December 18th we present a Stradivari Anniversary Concert. Here is Mrs. Whittall speaking at the 1937 Strad Concert. To all unseen friends who are listening in tonight, we welcome you. We are back together by the universal bond of the love of music. This collection of instruments that you will hear played upon this week were made by the great craftsman, Antonio Stradivarius. I held them in trust for a short time, now they belong to every one of you for they were given to our Government to hold and protect, further, in presenting these instruments to the Library of Congress it was my aim to give to the people of this country an opportunity to see and hear these rare Stradivari. They can be viewed at the Library of Congress by anyone who wishes to do so. They can be heard in concerts held in the Library and also through the medium of the radio by an even larger audience. If the appreciation and enjoyment of music in America will be advanced thereby the purpose of my gift will have been fulfilled. As you already know, the festival being held this week is to commemorate the 200th Anniversary of the death of Stradivari on December 18th. But it is not our intention to make you wait another century or two for a similar presentation, it is our hope that we shall be able to present a commemorative concert each year on December 18th and that arrangements will be made whereby you can all hear it. >> Michael Turpin: So that 1937 Concert happens to be the earliest one I could find in the collection. It featured the Gordon String Quartet, that's Jacques Gordon, the leader, the first violinist. I couldn't find a picture of the whole quartet, but we'll listen to a bit of that. Now we're going to do a little time travel, well, we've already done some - imagine it's a cold December night in 1937 and you can't get to the concert. Well, you might have turned on your radio, which might have looked something like that. Here is what you would have heard. >> The National Broadcasting Company invites you to the Library of Congress Chamber Music Auditorium in Washington, D.C., where an audience of music lovers has gathered to hear the first of a series of concerts commemorating the 200th Anniversary of the death of the celebrated violinmaker, Antonio Stradivari. This series is being presented here at the Library of Congress under the auspices of the Gertrude Clarke Whittall Foundation and the music at all of these concerts will be played on instruments made by Stradivari's own hand, including the rare quartet of two violins, viola and cello presented to the Library of Congress by Mrs. Matthew John Whittall. Today the participants are the members of the Gordon String Quartet - Jacques Gordon, first violin, David Saxon, second violin, William Linser [Assumed Spelling], viola, and Urum Benditski [Assumed Spelling], cello. And the work we are about to hear is the last of the series, the six quartets composed by Beethoven and known to all quartet lovers by its listing as Opus 18 Number 6, the Quartet in B Flat. [applause] The Gordon String Quartet in the Chamber Music Hall at the Library of Congress plays Beethoven's Quartet in B Flat Major. [ Music ] >> Michael Turpin: I'm going to hate fading out in this music, but a lot of it to get to, so. The recordings we've been listening to so far were made on acetate discs that looked something like this. This was the recording medium radio stations used to make broadcast transcriptions or air checks for sponsors. The discs were fragile and the acetate coating could separate from the aluminum base if they weren't stored properly. There were also other problems. This is one of ours, but you see around the edges the white stuff and here's a better example of what can happen. When I first started here I spent many, many hours, days, weeks, months transferring these recordings from the NBC Radio collection. And one of the things we did was we had to figure out how to clean them. We used various methods and some chemicals that aren't available anymore because they're not safe. [laughter] But and this was the '80s and, you know, we did what we had to do to get them cleaned. Also, about these discs, during the War, the Second World War, they used a glass base and, of course, that was a common problem in that there were many broken ones. Some we could put back together and some we couldn't. But these discs were never meant to be used for archival storage. In fact, in those days not much thought was given to storing sound recordings. Fortunately, much of the NBC Radio collection, including our concerts, survived on these discs, which are housed in our Audiovisual Preservation Facility in Culpeper, Virginia. Now Mrs. Coolidge understood the potential of this new medium called radio and its ability to reach vast numbers of people. Her relationship with broadcasters was not without its difficulties, however. By the mid-1930s commercial radio was pretty well established, commercial being the operative word here. Networks and local stations had to answer to sponsors and often those early concert broadcasts were interrupted by commercials. Also, they rarely broadcast a complete concert. Mrs. Coolidge was not happy about these interruptions and truncated programs and was not shy about letting her feelings be known. Still the music they did carry was reaching people and chamber music was reaching new fans or making new fans in America. Regular weekly broadcasts, including complete concerts, began in 1948, locally on WGMS - some of you might remember - and sometime in the 1970s they continued on public radio, where I first became familiar with them by listening on WFCR, Five College Radio in Amherst when I was a student at UMass. By the mid-1930s the Archive of Folksongs, which was part of the Music Division at the time, had acquired some disc recorders and a truck which they used to make field recordings documenting American folk music. Many of these recordings were made by the famous well-known folklorist, Alan Lomax [Assumed Spelling]. In 1938 Lomax invited Jelly Roll Morton, the great jazz pianist, to the Library and they spent two days in the Coolidge Auditorium recording Morton's songs and stories. Now these recordings are definitely R rated, but some of you may have heard them, but these recordings would become legendary and required listening for anyone interested in blues, jazz or folk music. Soon after that session the Music Division began recording the concerts in-house, which in turn led to the building of the Recording Laboratory in the early 1940s, and this is a slide of an engineer transferring a cylinder to tape. We have a very large collection of cylinders, Edison and others, and some of that work is still going on down in Culpeper. With a grant from the Carnegie Foundation and the establishment of a revolving fund the Lab was a self-sustaining entity within the Library, charging a fee-for-services, which included duplication of recordings for sale in the gift shop. Income was used to pay salaries, purchase supplies and maintain equipment. Now among the many ways Mrs. Coolidge left her imprint on the Library was by commissioning new music, particularly by American composers. The best known of these commissions without a doubt is Aaron Copland's Appalachian Spring. The work was a collaboration between the composer and dancer-choreographer, Martha Graham, whose dance company premiered the piece on the Coolidge stage in 1944. The ballet has been performed here several times since the premiere and will be again appropriately next spring. Mr. Copeland was here in 1981, celebrating his 81st birthday, and he was asked about Mrs. Coolidge and his famous work. >> Do you remember Elizabeth Sprague Coolidge? >> I certainly do and with much affection. Mrs. Coolidge really made her mark I think on American music in the consistent way over the years she established and continued to have here in Washington those excellent chamber music concerts. We really owe her a great debt, and I'm very glad you've given me the opportunity to say that in public. I've often thought it, and I wish we had more Mrs. Coolidge's around. >> That relationship is sort of symbiotic in a way because just as we, yourself, among the many composers owe a debt to her, I think her memory owes quite a debt to the man who composed Appalachian Spring for her. [ Applause ] >> You're forgetting Martha Graham, who created the work. [laughter] >> And it didn't even have a title, did it? >> No, it didn't. I can't imagine that being true any longer, I'm so used to thinking of it as Appalachian Spring, it never occurred to me that when I was writing it I didn't know what she had called it, she hadn't given it a name yet. So after finishing the work and mailing it back to her, when she already had it in rehearsal, the first time I saw her I said, Martha, what have you called the ballet? I called it Ballet for Martha just in my own mind. [laughter] >> That's exactly what it says on the front page of the manuscript, Ballet for Martha. >> That was a subtitle. [laughter] No, I didn't have a title. I was really putting Martha Graham to music. I had seen her dancing so many times. I had a sense of her personality as a creative artist. I had really in the front of my mind I wasn't thinking about the Appalachians or even spring, so that I had no title for it. The first thing I said to her when I came down to the rehearsal here in Washington was, Martha, what did you call the ballet? She said Appalachian Spring. Oh, I said, what a nice name, where'd you get it? [laughter] She said, well, it's the title of a poem by Hart Greene [Assumed Spelling]. Oh, I said, does the poem have anything to do with the ballet? She said, no, I just liked the title and I took it. [laughter] And over and over again nowadays people come up to me after seeing the ballet on the stage and say, Mr. Copeland, when I see that ballet and when I hear your music I can just see the Appalachians in spring. [laughter] I've begun to see the Appalachians myself a little bit. [laughter] [ Music ] >> Michael Turpin: Remember, this recording is still on disc acetates, and you might have noticed a little glitch and also the footfalls of the dancers on stage, interesting. So let's now talk about the Budapest Quartet, which I believe it was 1940, I'm not too sure about that, when they started, or '41. They became the first quartet in residence and started a 22-year relationship with the Library - 22 years, becoming the first quartet in residence, followed by an equally lengthy residency by the Juilliard Quartet. In 1945 the Office of War Information produced a series of documentaries called The American Scene. The Library was the subject of one of those films and it featured rare footage of the Budapest in concert. So let's take a look at that. >> But the roots of music in America go deep into the past and twist across oceans and continents. The Music Division of the Library can furnish the student with all kinds of materials, including priceless old manuscripts. This is the original score of a Bach Cantatas, and this a Mozart Quintet. Even the handwriting of a composer like Beethoven is of interest to scholars, but more important are the pen scratches by which he conveyed his immortal inspiration to the world. This is a manuscript of one of his string quartets. [ Music ] But the music that cannot be heard is dead. The Library with the help of a few generous patrons gives life to its music collections by presenting eminent artists in regular series of concerts. Typical of such occasions is this Sunday afternoon performance of the Budapest String Quartet, playing in the Library's collection of Stradivarius instruments. [ Music ] When Beethoven was born the United States ... >> Michael Turpin: Again, I hate to cut it off, it's such a great film. This whole film, it's actually only 20 minutes long and it can be found online, if you Google The American Scene Number 11, Library of Congress, it should be the first hit. It's on a website called archive.org and if you go right to the website, it's kind of hard to find it, but it's easier to Google it and you can go right to the film. So it's worth the 20 minutes to watch the whole film. They talk about other parts of the Library and what some of the other Divisions do and so forth. It's really pretty fantastic. So shortly after that film was made in 1945 audio recording technology was about to undergo a revolutionary change, but the story begins in 1928. That year a German Engineer by the name of Fritz Pfleumer discovered a method of recording sound by using iron oxide particles bonded to paper or cellulose film strip. This was the beginning of magnetic tape, but remember this was Germany and by the mid-1930s its use for spreading propaganda by the Nazi Party was rampant. Tape recorders were also a well-kept secret as the Party maintained strict control over all communication in and out of the country. So it wasn't until the war ended and US and Allied troops captured the tapes and recorders that the secret got out. Magnetic tape was a game changer as a method for recording sound compared to acetate discs. It sounded better, wasn't as fragile, and it could be edited. Tape allowed engineers and musicians the ability to do things that were impossible or very difficult to do with discs. When this new recording medium hit the States after the War it didn't take long for broadcasters to realize its potential. In fact, singer Bing Crosby was so interested he invested in a new company called Ampex, which along with 3M became the two dominant American suppliers of tape and recorders. This is a German Magnetophon recorder, one of the first ones manufactured widely. This is the Ampex tape reel and, of course, the venerable 440, which some of these machines are still in use down in Culpeper. With all the new technology we still have to be able to play the old formats, and it's getting a little more difficult now to find technicians that can repair these things but they're still working, and we have a couple good people down there keeping these things going. So back to the music. By the late 1930s the reputation of the Library's Concert Series was attracting major talent, like Dorothy Maynor, Leontyne Price, Leonard Bernstein, Itzhak Perlman and many others. In 1939 violinist Adolf Busch and pianist Rudolf Serkin performed here, and here's a bit of them doing the Beethoven D Major Sonata. [ Music ] We're back to acetate disc now. [ Music ] In 1940 soprano Dorothy Maynor became the first African-American artist to perform on the Coolidge stage. She was part of a three-day series of concerts commemorating the 75th Anniversary of the ratification of the 13th Amendment abolishing slavery in the US. The great tenor, Roland Hayes, and the Budapest Quartet also took part in those concerts. Here is Dorothy Maynor singing Depuis le jure from Charpentier's Opera Louise. [ Music ] Great voice. 1953 the great Leontyne Price premiered Samuel Barber's Hermit Songs with Barber, himself, at the piano. Here is the first song. [ Music ] [ Applause ] In 1963 Leonard Bernstein appeared with the Julliard Quartet in their second year of residence for the Schumann Piano Quintet, and I want to mention this recording is also available commercially, as is the Dorothy Maynor, you can get them both on Amazon or your favorite music outlet. So we'll listen to Lenny. Having a little fun with the tuning. I don't know if this on the record, but then they launch into the Scarzo [Assumed Spelling], which they take it really fast tempo. [ Applause ] [ Music ] That's Lenny. [ Music ] I think we have to cool the piano off after that. [laughter] We might really. Okay, let's - jumping ahead now to 2008, but another major group that had a long residency here was the Beaux Arts Trio. [ Music ] A lot to get through here. That you may have noticed, some of you may have noticed that was a stereo recording, obviously, by the mid-'60s, I guess, we started recording in stereo. Now we're back to 1981 and the great Itzhak Perlman, who joined the Julliard for a performance of the Chesong [Assumed Spelling] Concerto in D, the pianist is Jorge Bolet, and this was one of the first concerts I worked on. [ Music ] By the 1990s we begin to see some diversity in the concert offerings. Now jazz was never a staple here, but was offered in small doses here and there. I was surprised to learn that W.c. Handy's St. Louis Blues was on the program in 1929, but as much as she championed new music Mrs. Coolidge was apparently not a fan of America's most original art form and reportedly rejected a pitch for Benny Goodman to perform here. That's in the bar book [Assumed Spelling]. Nevertheless, jazz did eventually make its way into the concert schedule and into our collections. In 1993 the Music Division acquired the first collection of a major jazz artist, Charles Mingus. Mingus was one of the most important and influential musicians and composers of the post-Bop era. To celebrate the acquisition the Mingus Big Band was invited to perform, however, it didn't happen on the Coolidge stage. The Auditorium and most of this building was undergoing major renovations at the time so for a few years concerts were presented in other venues, mostly at the National Academy of Sciences Auditorium, which is just down the street on Constitution Avenue. So this Mingus Big Band concert was different in many respects. Of course, Charles Mingus passed away in '79, but so this was sort of a tribute band and the bassist, I think his name is Michael Formanek [Assumed Spelling], is playing Mingus' bass. It's a Lionhead bass. I don't know if you can see it, you probably can't see it much in that picture, but it was a great instrument. And this was also the first multitrack recording that we did. Actually, I didn't do it, we hired a mobile truck to do this recording. So this is the Mingus Big Band playing one of his pieces called Boogie Stop Shuffle. [ Music ] Fade out on these things, but this thing goes - the three trumpet players get into some trading fours and they get into an epic battle. It was really a memorable evening. Since that time we have, the Library has acquired many jazz collections, those of Ella Fitzgerald, Gerry Mulligan, Dexter Gordon, Max Roach, Billy Taylor and many others. The Coolidge Auditorium reopened in the fall of 1996 and part of the renovation included new audio and video equipment. And this is a shot of the recording booth back stage, that's where you'll find either Jay or me on concert nights. And in 2000, the early 2000s, I was able to order our first digital multitrack recorder. And this was one of the first ones available, it records up to 24 tracks to a hard drive and each track is saved as a wave file. I don't want to get too technical, but basically you take the hard drive, once the recording is done you take the hard drive out, dump it into a computer, and if you have editing software like this you can mix and edit, all without using tape. As someone who came up in the analog era, I remember a razorblade and splicing tape and marking and having little pieces of tape on the floor, and hoping that I didn't have to pick one up and put it back in. [laughter] It's the computer makes it much, much easier and more efficient, and so it's just much, much faster to edit this way. So by this time it was clear that our concerts were going to consist of more than string quartets. Since that Mingus concert we've presented other big bands, small jazz ensembles, jazz rock hybrid orchestras and a diverse list of artists, much too long to name. In recent years the Library created the Gershwin Prize for Popular Song, which culminates in a large-scale, multi-talent concert. Some of you may have heard Willie Nelson is getting the prize this year, and that concert will be coming up in a couple weeks, but it won't be here, it'll be at Constitution Hall. We've also formed partnerships with ASCAP and CMA, the Country Music Association, each featuring their own big concerts. So the challenge of recording so many different kinds of events is formidable, but I'm fortunate to have a lot of help. Presenting these concerts is truly a team effort and we have a great team in the Concert Office. I also want to mention and thank our sound contractor, John Regan [Assumed Spelling], some of you may know, and his RMS Team. You'll usually see John in the Auditorium for many of these large-scale events, like the ones I've mentioned, and having him take care of what we call house sound, which is the sound that you hear in the audience, allows me to focus on getting a good recording for the collection. So I wanted to make sure that I've thanked him publicly. So in closing let me say what a pleasure it's been for me to be part of this, to see positive changes over the years, getting to meet and work with great musicians, getting to play with lots of new tech toys and getting to work with a great group of smart and talented colleagues. I also want to thank all of you, the audience, and our donors for supporting concerts from the Library of Congress because without you there would be no Concert Series. So clearly we could be here all night listening to recordings, but we have a great live concert for you to listen to by the Bach Collegium of Japan. So I will leave you, if I can switch over, with a little video montage that I put together of some recent concerts just to give you a little more of an idea of the variety of things that we do here. [ Music ] [ Applause ] >> Michael Turpin: Thank you. And I guess we have time for a couple questions or two, anybody? Well, we're going to wait for a mike. I know you have some. [laughter] >> Could you just quickly, briefly describe the current standard of preservation? Are you digitizing or have you digitized all older materials, audio and visual? >> Michael Turpin: Yes, not all, we're talking about millions of items in the collection. >> So what's your prioritization? >> Michael Turpin: Well, the priority is pretty much up to the head of the Recorded Sound Office, his office is down in Culpeper. I think that they will do some like digitizing on demand, in other words, if you come in and you want to listen to a Julliard concert from 1969 or something they would pull that and digitize it. The standard for digitization is high resolution. For the technically minded it's 96, 24, 96 kilohertz, 24 byte resolution, which is much higher than CD resolution. CDs are 44, 16, 44 kilohertz, 16 byte. The higher the byte rate and the higher the sample rate the more depth there is to the audio, so it's sort of like going from standard definition, which these videos, unfortunately, our video is not high definition yet, but if you've seen high-def video, when you go back to standard it's kind of, you can - the difference is obvious, so I mean. >> I remember the broadcasts, the radio broadcasts well, Julliard and others. >> Michael Turpin: Yes. >> And any chance that it'll ever come back so that we can spread it all over the radio? >> Michael Turpin: The radio ... >> TV? >> Michael Turpin: Yes, well, it really comes down to funding, unfortunately, and the climate we're in now, trying to get anything funded is a little difficult. We have produced a couple of series of radio broadcasts that are edited, one-hour programs of highlights of concerts. Again, we're not - we can't put a whole concert together, but these are being produced by an outside company called CD Syndications, and they also do a lot of work with the folks over at Wolftrap [Assumed Spelling]. And you may have heard - I think they've been on - they were on last spring, concerts from the Library of Congress, I think WEDA [Assumed Spelling] broadcasted them. So, hopefully, that will continue. I think we're going to do another one next year. Anyone? >> What was the biggest challenge you faced in recording a group on the Coolidge stage? >> Michael Turpin: It depends on the group. I mentioned John Regan, our contractor. It's really great to have someone in the Auditorium doing house sound. If you have a jazz group like Gregory Porter you've got to have someone doing house sound because you've got drums, you've got a bass with an amplifier, you've got a singer, you've got, you know, it's a totally different dynamic than a string quartet or a baroque ensemble, like you're going to hear tonight. These kinds of concerts don't really require any amplification. You won't see any amps on stage or big speakers or anything like that because the hall - another thing, the Coolidge was designed specifically for chamber music, so it is a challenge to get - anytime we get a drummer in there or horn players or amplified instruments it is difficult to get a good balance. But the recordings come out great because I'm sort of - we do separate mixes. John does his mix for the house, I do my mix for the recording, and I have a lot more control over what goes on the tape or the disc, the computer, if you will. So, but, yes, it's a challenge. >> Were you the recording engineer for that Copeland 81st birthday concert? >> Michael Turpin: I was not, no. >> Okay. >> Michael Turpin: I had just started in '81 in the Recording Lab so I was just learning my way around and ... >> I was going to ask if you ever got to meet him and what your impressions were? >> Michael Turpin: Did not, did not. >> Another technical question, if I may? How are you planning to archive the archives? Obviously, the hardware will fail eventually, so archiving the hard discs, optical discs or any other media? >> Michael Turpin: We're doing, there's a tape backup system and it's called, a system called Data Migration, so as the data collects on different servers it's automatically transferred to other servers and to tape. And they're - I'm a strong believer in backups, even on these recordings. Every concert I record at least three or four different ways so that if there is a failure we have it some other way, but the equipment has been ... [ Inaudible ] >> Michael Turpin: I'm sorry? [ Inaudible ] >> Michael Turpin: Yes, yes. The converters we use, using now an Apogee [Assumed Spelling], I forget the model number, but it's a very high resolution converter, analog-to-digital converter. >> Since you're recording digitally at this time and you're recording every performance digitally, and since digitally it's available within minutes of the ending of the recording can these recordings be made available on the Library of Congress website? >> Michael Turpin: They can be, but the problem is not the technology, the problem is the artists, the composers and rights, copyright issues. We can't just put something up, it has to be approved, the artists have to approve it, and we've got to get all the clearances. Remember, the Copyright Office is here in the Library of Congress. [laughter] So we are very aware of copyright issues here. So I would love to put these up right away, but we can't do it. >> Thank you. >> Michael Turpin: Yes? >> Did Gershwin compose to the Library? >> Michael Turpin: I'm sorry, did Gershwin? >> Compose? >> Michael Turpin: Compose for the Library? [ Inaudible ] >> Michael Turpin: I don't think so, I don't think there were any commissions of Gershwin. We do have the Gershwin collection here, you know, in of course the room across the hall, and we had a big Gershwin Festival when the Coolidge reopened in '97 I think it was or '98. Yes, yes, sure. Anyone else? You want the mike? We're trying to get all this on - we're recording all this, so we record everything here. >> Okay. How many instruments are in the Stradivarius collection? >> Michael Turpin: I'm not sure. Michelle can answer. >> Six. >> Michael Turpin: Okay. I don't know, I don't play so not the violins anyway. They're beautiful. Yes? >> So can you tell us a little bit, it sounded like you were doing some of the audio recovery restoration early on when you were talking about various things, the solvents and such, so have the resources - obviously, the Culpeper Facility didn't exist at the time. >> Michael Turpin: Right. >> Can you describe a little bit if the resources when you started and versus the current state? >> Michael Turpin: Versus what's now? >> Yes? >> Michael Turpin: Well, there's a lot more available now. Back in the '80s there were about five of us engineers working during the daytime. We spent most of our days transferring the NBC Radio collection because it's the largest audio collection we have, over 100,000 of those acetate discs. And it covers just about everything NBC did from the late '30s into the '70s, that's a long time. And we're talking about complete days of broadcasting, and you'd start off with the morning, the farm report in the morning, and then the morning news, and then into the daytime talk shows and the soap operas, evening primetime, the Jack Benny Show, Bob Hope, all of that stuff is in there, so. And as far as what we would do, a lot of the discs were in pretty good shape. There were a few of those that had the - we called it exudation [Assumed Spelling], it's sort of like a white, powdery stuff that sort of comes out of the acetate, and we had various methods of cleaning. One of them was, I hate to say it but we were using Freon at the time and cannot use Freon anymore. But, again, this was the '80s. But there are other methods. I'm not familiar with exactly what they're doing in Culpeper now because I'm not down there, but I think if you dig around on our website you can probably find some information. >> When was it built? >> Michael Turpin: When was it built?
