At 0:51 .. Mozart , his great idol :-) ... simply brilliant the opening of the first movement ... the contrasts, the emotions .. delicious. It is like he is talking to Mozart saying ... here, this is where we need to go .. to go beyond your genius. Incredible achievement .. he bridged the gap to modernity. Zimmerman has a very effortless style, that makes you forget his playing and concentrate on the music. I have my own favorite though (Katchen on Decca, the best kept secret)
