I feel that if you go out and get a complete set of 32 Sonatas by any of the following pianists, you can't go wrong:
Kuerti, Goode, Sherman, Schnabel, Brendel, Rangell , Anne Fischer & Gieseking to start.
Did Sherman, Rangel & Gieseking ever record a complete set ? Obviously I have been sleeping at school.
Besides I would not dare to recommend a complete set by Kuerti, Brendel (except perhaps the VOX cycle) and Gieseking.
