Yesterday I received an email from someone who used to be a researcher at CCRMA at Stanford about this:
--- You may find interest in following the discovery of a possible large-scale hoax in classical music.
I have been analyzing the performances of Chopin Mazurkas (http://mazurka.org.uk) and have been noticing an unusual occurence: the performances of the same two pianists always matched whenever I do an analysis for a particular mazurka. In fact, they matched as well as two different re-releases of the same original recording.
We were keeping the identity confidential due to strict libel laws in the UK and slowly building up a case. One CD set being a match could possibly be an innocent mistake, and if the record label lost business due to insinuations related to our findings... However, the story broke this past Thursday afternoon on the Gramophone website:
Last week, a music critic of Gramophone put a CD of Joyce Hatto's performance of the Liszt Transcedental Etudes into his CD-rom drive. The iTunes program then informed him that the pieces on the CD were correct, but the performer was different. He had that other CD and listened to both and could tell that the sounded very similar to each other. He then found using iTunes another match with Joyce Hatto playing Rachmaninov piano concertos, and again he had the original CD and could not tell a difference between them. He sent them to Pristine Audio to be analyzed by Andrew Rose, who confirmed the matches:
Andrew subsequently discovered that the Hatto performances of the Godowsky Chopin Etude Studies were also from a previously released commercial CD (although recent reports indicate that some of the tracks on the CD set are by an additional performer Marc Hamelin).
The day after the initial disclosure on the Gramophone website, CHARM (http://www.charm.rhul.ac.uk) released their findings which it had been collecting on the similarities of the Chopin mazurkas, since there was no longer any legal concerns related to releasing our corroborating findings.
It is interesting to note that the Mazurka performances of Joyce Hatto could not be identified by the CDDB method used by iTunes to uncover the first two matches found by the Gramophone critic. The ordering of the mazurkas had been changed on the CDs, and the mazurkas were allocated differently on the two discs so that the track counts did not match. In addition, each track was timestreched by differing amounts. In the three mazurkas that I have examined in detail, the time stretching was -0.7%, -2.8%, and +1.2%. The fact that different amounts of time stretching was applied to the separate tracks leads to juicy circumstantial conclusions. It is interesting to note that Andrew Rose discovered that the Godowsky Studies had been slowed down by an incredible 15%.
Six of Joyce Hatto's CDs have been identified as copies of existing commercial recordings (as of Sunday night): three by Gramophone/Pristine Audio; one by CHARM; one by arec.music.classical.recording contributor 12 hours after the Gramophone news (so his claim to have know earlier is most likely correct); and 1 additional matching on Sunday for a source to the Chopin Etude CD set.
Hatto's mostly complete Concert Artists discography and a list of the currently identified original sources are available on her entry in

A couple of months ago, Luiz André Barroso of Google gave a talk at Stanford about this very topic. Unfortunately the talk wasn't recorded, but here's a summary: http://cs343-spr0607.stanford.edu/index.php/Writeu ps:Luiz_Andr%C3%A9_Barroso
This is also bad news for the Canadian TiVo users because the unofficial service relied on feeds from labs.zap2it.com. argh.
