Sokolov has a big musical personality, and I also love his playing. In the last concert of his that I saw, in Munich, he played all Baroque music as encores - Couperin, Rameau and Scarlatti.
I also heard him play Schubert D959, and actually it was the one thing I didn't like. It was quite sentimental and not orchestral at all, so it sounded a bit fussy and puny. More like a very, very long Chopin nocturne than a Schubert sonata. Well, diff'rent strokes for diff'rent folks!
