Recorded Horowitz

An Index of Released & Unreleased Recordings
Prepared and Compiled by Christian Johansson

 

 

Chronological Section

 

The Recording Index on this website is an attempt to catalogue all surviving recordings of the legendary Vladimir Horowitz. The index consists of two separate sections - one by composer which I have chosed to name the Alphabetical Section, and another which lists the recordings in chronological order which is called the Chronological Section. All recordings listed in one section are naturally listed in the other as well, but in order to make the sections as user-friendly as possible there are a few differences in concept between them. I have been more generous with discographical info in the Chronological Section as such would take up a lot of space in the section by composer and thus disturb the flow and readability of the page, but on the other hand the section by composer generally has more detailed info on specific recording dates and number of takes from commercial recording sessions where several takes recorded days - sometimes months - apart were used for the commercial release of a work. This is to reduce the number of notes & references to other sessions in the chronological section to a minimum.
The index as a whole aims to be as complete as possible, but even more importantly 100% accurate & reliable, and to achieve this I have used the following template when creating the index:

-  First of all I have only included recordings I am sure exist as I have a copy myself of the recording, or know someone trustworthy who does. I have not listed any recordings based on rumours alone.

-  Material from commercial recording sessions have been catalogued through the recording logs for the sessions, and through help from people with access to the actual tapes or discs in cases when the information given in the logs has been inadequate.

-  All dates and locations are given as they are known to me through my sources or through the fruits of my research. I have not made any guesses myself, and I have decided to leave assumptions to the reader.

-  Fragments of works from rehearsals, warm-ups, private sessions and similiar have been deemed irrelevant for the discography and have not been included. Notes to a few which might be of particular interest can be found in the Appendix at the end of the page.

All commercially released recordings are written in black and have a reference to the label & catalogue number of the issue in the alphabetical section. When recordings have appeared in more than one commercial issue only one catalogue number has been quoted (there are a few overlaps though as all commercial items included in the index have been listed in completion) - generally to the best, most recent, or most accessible release. All catalogue numbers refer to a CD release unless other is stated.

Material that has never appeared in any commercial release is written in grey, and have an indication in bold text to the type of the recording. There are seven kinds of commercially unreleased recordings, a description of each follows below.

Unreleased Recordings
These are recordings which were professionally recorded by Horowitz's current record company, but which have by one reason or another not been released. The reasons for this are innumerable, but in most cases they have remained unreleased as Horowitz was dissatisfied with the recording and did not approve it for commercial release, or (especially in the early recordings) perhaps as the recording engineer was dissatisfied with the technical quality of the recording and did not approve it for release (yep, both the artist's and the engineer's approval were required before a recording could be released). Fortunately most, though not all, of these recordings are preserved in the vaults of the record company responsible for them (see the Chronological Section), and we can only hope as many of them as possible will be released in due time now when they're not controlled as tightly by Horowitz or The Horowitz Estate anymore. The best way of pushing for this is to buy Horowitz's CDs and DVDs to show that there is a public interest in Horowitz's recordings and to provide funds for further releases.

Copying and ripping commercial CDs is *NOT* to support the record companies!!

Private Recordings
Somewhere duing the winter of 1944/1945 Horowitz signed a contract with Carnegie Hall's Recording Service to record his recitals there. The recitals were recorded in completition, including encores, and pressed on LPs for Horowitz who used them to study and analyse his playing. All Horowitz's recitals in Carnegie Hall except one were recorded between March 1945 and March 1951 when RCA took over instead. These are nowadays known as the "Yale Recitals" as Horowitz donated them to Yale University during the 1980s where they are still stored. All unique repertoire these concerts contain except Balakirev's Islamey, Liszt's 2nd Legend, and two Preludes by Kabalevsky was released by RCA in the 1990s on two CDs called "The Private Collection", but the complete concerts remain unreleased and are referred to as Private Recordings in this index.

Radio Broadcasts or TV Broadcasts
These are recordings which have been recorded by radio and TV stations and are now preserved in their archives and/or on VHS or audio cassette tapes recorded from the broadcast by amateurs.

Amateur Acetates
From the 1930s and onwards it was actually possible to make private home recordings on a machine which could record a few minutes of sound on discs called acetates. These machines were very rare, did not produce recordings of any greater quality, and probably cost a fortune in their day, but a young lady in Chicago on very good terms with Horowitz, Rachmaninoff, Kreisler, Cherkassky, Toscanini and a whole horde of other artists had access to one and used to recorded them in small mini-recitals for a set of a invited friends in her living room which she liked to arrange. So far, this lady's acetates are the only known ones with Horowitz.

Pirate Recordings
A pirate recording is a recording made by some innocent looking guy in the audience armed with a microphone, secretly and illegally recording the performance. To the best of my knowledge the first recordings of this kind started to appear in the New York area during the spring of 1965 (the first known pirate with Horowitz was recorded in New Haven on November 13 1966), and then increased in number up to the early 1970s when tape recorders had become so small and so cheap that just about anyone could afford the equipment needed to tape a concert without any greater risk of being discovered. There are actually also a few video pirate recordings from the 1980s, made by someone who has managed to smuggle in a videocamera in the hall and have been brave enough to film from his seat, probably with a Bible in his free hand praying that no one will look his way.
    Pirate Recordings vary from case to case in soundquality, from "quite good" all the way down to "only barely listenable" depending on which type of microphone and taperecorder that was used, the medium the recording was preserved on (always open reel tapes or cassettes in Horowitz's case, but of variable qualities & brands), where the microphone was placed during the recording, and how far from the stage the pirate was sitting. And of course also how many generations away from the mastertape the copy one has is as all of these have been passed around in analogue formats before CD burners were available & affordable to the average person.
    A few pirate recordings have been released on CD by Music & Arts and Living Stage for instance, but most of them remain unavailable and only exist in private collections of tape collectors and fervent Horowitz enthusiasts.

Bootlegs
A bootleg is defined here as a professional recording that was made without permission from or even knowledge of Horowitz, his agent/manager, or his record company. Well, a "professional pirate recording" then so to say, though not recorded from a seat in the audience of course.

Press Tapes
During Horowitz's press conferences during the 1970s & 1980s journalists often brought a tape recorder and recorded the conference to save them from writing it down or making notes. Some of these tapes have survived and have been passed on to Horowitz enthusiasts.

August 27, 1942: Hollywood Recording Studio, California (Studio)

• Tchaikovsky:  Dumka - Russian Rustic Scene, Op.59*
• Chopin:  Waltz in D-flat major, Op.64 No.1 (Minute)
• Chopin:  Waltz in C-sharp minor, Op.64 No.2
  
      * Only the second part was used for commercial release

September 10, 1942: Hollywood Recording Studio, California (Studio)

• Scarlatti:  Sonata in A major, K.322
• Scarlatti:  Sonata in A major, K.533
  
      - Note: The recording logs for the Sept.29 & Oct.9 sessions do not specify the Scarlatti items, they are only labeled as "Two Sonatas in A major". However, I have been convinced ONE of these sessions had the K.322 and K.533 Sonatas, and have assumed the other session contained the same Sonatas.

October 9, 1942: Unknown location (Studio)

• Horowitz:  Variations on a theme from Bizet's Carmen
• Scarlatti:  Sonata in A major, K.322
• Scarlatti:  Sonata in A major, K.533
  
      - Note: The recording logs for the Sept.29 & Oct.9 sessions do not specify the Scarlatti items, they are only labeled as "Two Sonatas in A major". However, I have been convinced ONE of these sessions had the K.322 and K.533 Sonatas, and have assumed the other session contained the same Sonatas.

April 25, 1943: Carnegie Hall, New York City, New York (Live)

• Tchaikovsky:  Piano Concerto No.1 in B-flat minor, Op.23
      - Arturo Toscanini/NBC Symphony Orchestra

Professional Bootleg: Probably November 25 or 26, 1943: Carnegie Hall, New York City, New York (Live)

• Rachmaninoff:  Piano Concerto No.3 in D minor, Op.30 [first minutes missing]
      - Arthur Rodzinski/New York Philharmonic Orchestra
  
      * This recording is labeled as being from April 23 or November 25, 1944 - both dates are almost surely wrong. There was a concert in Carnegie Hall on November 25, but it was Piatigorsky playing Haydn's Cello Concerto, and not Horowitz playing Rachmaninoff's Piano Concerto. April 23 appears to be entirely wrong, and the NY Times' microfilm archive backs this up. Furthermore, the reviews for the November 1943 performances fit exactly with the performance itself.

      * One source claims that this recording was released, and the October 11 recording is the unreleased one. As if that wasn't enough, EMI themselves say that the commercially issued version of both the Nocturne and Impromptu were actually recorded on October 11 1935, which doesn't exactly make things easier! No documents supporting any recording session at all on October 11, 1935 have been found though, and I think both these claims are errors. As far as I can tell, the actual date of the released recording is October 11, 1951 - just as Jon Samuels' stated in his discography - and there were no recordings made at all on October 11, 1935.

• Tchaikovsky:  Piano Concerto No.1 in B-flat minor, Op.23
      - George Szell/New York Philharmonic Orchestra

- There are some question marks about the origin of this recording. It is listed in RCA's recording logs and should therefore have been taped by them, but last someone looked for it it wasn't in their archives. Furthermore Harold C. Schonberg claimed that Horowitz's producer at the time, John ("Jack") Pfeiffer, first heard this recording through a tape that was in circulation at the time among collectors and immediately wanted to release THAT under RCA (but couldn't as Szell was under contract with Columbia). Surely his team at RCA couldn't have recorded this without his knowledge.
Another rumour is that it was Columbia who taped the concert, but they claim they don't know anything about that, and rightly so if they did as they in that case recorded it without the knowledge of RCA which Horowitz had an exclusive contract with at the time of the recording.

Due to the excellent sound of the recording I strongly doubt it was recorded privately on reel tape from a radio broadcast, but even apart from Schonberg's Pfeiffer story above there are shreds of evidence supporting that it is a possiblity. The Orchestra, the NY Philharmonic, was under contract with the Canadian Broadcasting Corporation (CBC) that season and had right to broadcast their concerts, and they probably wouldn't have liked to miss an occassion where the perhaps world's most celebrated soloist at the time appeared with them, and to privately record from the radio was not impossible at all even as early as 1953. If they did record & preserve the performance another possibility is that someone working at CBC smuggled out a tape of their uncompressed archive tape, and that's what reached circulation, appeared on private LP pressings, and eventually on CD through small pirate labels. If this is so however, the archive tape is not in their vaults anymore as it seems. *sigh*

YET another possibility is that this is in fact one of the first pirate recordings made. In the early 1940s Carnegie Hall opened a recording service for the artists playing there (which Horowitz used between 1945 and 1951, producing the so called "Yale Recitals") and - I don't say this is what happened, but it is a possibility - it's not unlikely that a private person with a wallet large enough could persuade them to turn on the microphones without both Horowitz's & RCA's knowledge and then press a one ex LP of the performance. I have not heard of any bootlegging of this kind from as early as 1953, but it is known to have happened frequently in numerous halls from the 70s and onwards (to take just one example with Horowitz, Minneapolis 1976) and there's really no reason as I see it why it couldn't have happened during the 1950s as well.

Well in a nutshell then, it's a damn troublesome recording for a discographer who naturally have to know everything about every recording. =)
The facts are presented above, if I may now make an "educated guess" of my own based on what we know I would say that this recording was taped by RCA and leaked out to a number of collectors either through the recording engineer or Jack Pfeiffer himself, who in that case probably made up the story he told Schonberg to cover his blunder of having put it in circulation among "outsiders". If this is the case, the reason why the tape of the concert wasn't found in their archives when Jon Samuels prepared his discography probably has a simple explanation too. RCA totally organised and inventored their vaults in 1996-1997, but before that they had been in a terrible disarray ever since the 1940s. When preparing the set "The Horowitz Collection" for instance they often had to work from copies as the masters couldn't be found, and in some cases they even used, or had to use, alternate takes as the approved take either was mislabeled or misplaced. It is therefore not unlikely at all that the recording WAS there, but not where it was supposed to be.

      * According to an article by Jack Pfeiffer ("Manhattan Holiday" - High Fidelity, October 1957) these recordings were made over 4 sessions early in 1955 and not on May 9 & 14, 1956 as generally believed. The finished product of these sessions was released in the fall of 1956, and there are production sheets for the Scriabin LP dated May 9 & May 14 1956 so at some stage it seems as if someone mistook the production sheets for recording logs and therefore dated these recordings erroneously to May 9 & 14, 1956. Recording logs are generated at the beginning of the recording process, when the music is captured on tape. Production sheets were typed at the end of the recording process, after the music had been recorded, the artwork selected, and the notes written - just prior to the actual release date of a new recording.

October 1956: Unknown Location (Studio)

• Beethoven:  First movement from the Sonata in C-sharp minor, Op.27 No.2 (Moonlight)*
  
      * This recording has caused me some headache, but here's what I believe was its reason and fate: 
  Horowitz recorded the entire Sonata on June 5, and approved it for commercial release. Later that summer he had second thoughts about the tempo in the first movement, and decided - much to the frustration of RCA's recording team who had to drag everything back to Horowitz's appartment - that it needed to be re-recorded if he was to approve the release of the album. He did so somewhere in October the same year, but only the first movement, and to the best of my knowledge the first movement from the June session remains unreleased.
  Many thanks to Hank Drake for helping me sort everything out with this troublesome recording!
