Well...color me amazed. I couldn't find Paul Lewis's great recording on Youtube (which is one of the best, owing to his long-arched conception bringing coherence to the musical semantics). But I spotted this by Lazar Berman. I'd never heard it. I was curious. It has a different feel than the Lewis one, and it made my hair jump up and my eyeballs spin. He takes CHARGE of this sonata! And his playing reminds me a little of Richter, in the way measures are isolated for intensest retrieval of musical possibility. That is a different approach than Lewis's more holistic traversal.
