Gramophone has an article about the late English pianist Joyce Hatto, an obscure pianist who rose to fame after she died when her husband released several of her recordings on a tiny recording label. But computer analysis has revealed that Hatto probably didn't play the music on the CDs.
Several days ago, another Gramophone critic was contacted by a reader who had put a Hatto Liszt CD -- the 12 Transcendental Studies -- into his computer to listen to, and something awfully strange happened. His computer's player identified the disc as, yes, the Liszts, but not a Hatto recording. Instead, his display suggested that the disc was one on BIS Records, by the pianist L·szlo Simon. Mystified, our critic checked his Hatto disc against the actual Simon recording, and to his amazement they sounded exactly the same.Link (Thanks, Jennifer!)
