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

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, 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.

- Note: This broadcast has the appearance of being recorded live, but the works Horowitz "plays" are nothing else than his commercial recordings of the works (from 1950) with spliced in applause at the end. The three works (listed above) were all to be commercially released later that year and this broadcast must have served terrifically as PR for the new LP. So, no new performances here sadly.

* 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.

* 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.

A huge thanks to Robert McAlear for this info.

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!

* A company called “Unitel” was hired to shoot a Vladimir Horowitz documentary in 1974. Howard Taubman was to have been the producer (or the executive producer). The first (and only) filming session was held on May 5. Horowitz played through the full program of his concert to be held the next Sunday in Cleveland.

Private tapes reveal that Wanda Horowitz became incensed by the way the Unitel camera crew conducted the filming on May 5. Specifically, she complained that the crew occupied many more rooms than agreed, used flood lights that were far too bright (causing Horowitz discomfort at the piano), and otherwise violated the terms to which she had agreed. Several days later, Wanda phoned Unitel in a rage, resulting in the cancelation of the second film session (scheduled for May 19), and ultimately the documentary itself.

The two selections from the May 5 film that have been released were included in “Horowitz: A Reminiscence” (2003).

Please note

There are many unreleased commercial recordings made between 1966 & 1989 that are yet to be catalogized, and there are probably also more pirate recordings hiding in music enthusiasts' private collections that I have not found yet or that have never been in circulation among collectors. An index as this one will never be entirely complete, it can't be, but I will do my best to update it as soon as I find or get info for new recordings to make it as complete, reliable and up to date as possible.

Appendix

Notes for collectors on Horowitz’s Studio Recordings:

According to Christian Johansson, the following unreleased recordings have leaked in the last decade, reaching a few collectors (but not me). These are:

· Poulenc: Presto in B-flat major (1946)

· Scarlatti: Sonata in G major, K.455 (1947)

· Scarlatti: Sonata in E major, K.380 (1947)

· Scarlatti: Sonata in F-sharp major, K.319 (1947)

· Mussorgsky: Pictures at an Exhibition (1947)

Christian notes:

"The dates for these are however highly questionable, with the exception of Mussorgsky. This in particular as RCA's logs show no record of having recorded most of these works during the given year. The Mussorgsky must be from 1947, but whether it is the unreleased May 15 recording or alternate takes (or for that matter, issued takes) of the commercial release still needs to be looked up."

There are live recordings from the early 1950s of the 2nd movement from Bach's F minor Concerto as well as his Chorale Prelude "Nun freut euch, lieben Christen" (BWV 734) in circulation that have been attributed to Horowitz. The actual pianist is yet to be identified, but it is sadly not Horowitz playing.

Two unedited recording sessions where Horowitz plays extracts from Chopin's Op.10 No.4 Etude and the 3rd movement of Beethoven's Waldstein Sonata have leaked out and are in general circulation among collectors. They both stem from the early 1970s, but no one seems to know exactly from which session. An educated guess however would be that the Beethoven one is taken from December 20, 1972 and Chopin either from February 8 or February 15 1973 - both recorded for CBS in their 30th Street Studio in New York City.

Two versions of the Beethoven session circulates however - one of them has some 2 minutes more material than the other.

Although many rehearsals, warm-ups and other practice sessions have been recorded with Horowitz over the years both professionally and by amateurs, only two have reached general circulation among collectors as far as I know - the February 25 1978 rehearsal for the White House recital the following day, and the semi-public April 18 1986 rehearsal at the Moscow Conservatory.

Christian Johansson and I are both deeply grateful to Caine Alder & Robert McAlear for their corrections & additions to the unreleased commercial recording sessions. I’d also like to thank Robert Ginalski and Joe Patrych for their extensive input, and Christian himself for contributing his research.
