There is a lot of Schnabel's Beethoven piano Sonata(comp) release on the market. Can anyone tell me whether they are all come from the same recording? I mean the recording from 1932-1935 in EMI. At least I know Pearl is. But what about Dante and Arkadia's release? Does anyone compare the performance if they are different? Thanks a lot. Jiang Fu <[log in to unmask]>
