The one I have was recorded at The Maltings, Snape, 14 June 1999. Is that the one you got? He has a nice feel for this music, though it does seem a little rushed in spots. I think Richter has ruined me for other interpretations (and he didn't even record this one!), he plays these sonatas significantly slower than others. I like it because it gives you time to take it all in. I have a nice performance of this by Grigory Sokolov. He's slower in every movement except the last. This is an approach that Richter took to the Schubert sonatas. I wonder if Sokolov was influenced by Richter?
