The big story in the classical music world this weekend is the apparent hoax of pianist Joyce Hatto.

Hatto, who died in June 2006, has been the object of much critical praise over the last year or so for a series of recordings produced by her husband and released on the small Concert Artist label.

Now, Gramophone Magazine has discovered that several of Hatto's recordings are almost certainly performances by other pianists. There's a lot of research left to be done in upcoming weeks to determine how much (if any) of the music released under Hatto's name is actually performed by her, and how much is stolen from other recordings. As Gramophone says, this story will be with us for a while.
