The late classical pianist Joyce Hatto released over 100 recordings shortly before her death in 2006. According to Gramaphone magazine,

To love Hatto recordings was to be in the know, a true piano aficionado who didn't need the hype of a major label's marketing spend to recognise a good, a great, thing when they heard it.

But it appears Hatto was not the virtuoso some believed. Using a variety of technology (including the simple act of ripping one of her CDs using iTunes), Hatto and her husband/producer are being accused of stealing other musicians' recordings.

[...]

Gramophone then sent the Hatto and the Simon Liszt recordings to an audio expert, Pristine Audio's Andrew Rose, who scientifically checked the soundwaves of each recording. They matched. "Without a shadow of a doubt," reported Rose, "10 of the tracks on the Liszt disc are identical to those on the Simon."

The folks at Pristine Audio have posted a series of articles about their research and findings, complete with side-by-side audio comparisons and images of wave forms and equalizers.

I don't know why I find this fascinating, seeing as I'd never heard of the artist before now and don't listen to a lot of classical music.

Perhaps I just like a good mystery.
