Interesting listening to you. I decided in my autumn-winter years to finally learn this. I've done most of the sonatas with the exception of this and the 106. To me, it's the ultimate in Beethoven. At once impossible, yet very accessibile. I've only listened to the first movement, so far. a couple of times, actually. I was curious to how you worked out some of the technical problems. With the exception of the opening octaves, I divide a lot between the two hands, when it doesn't affect the outcome. (I'm curious to see how you do the final trills!) I think you play this honestly and very brilliantly. That is, your brilliancy isn't an end to itself. It does express something more. On the whole, I think the allegro should always be at the same speed, to give the movement more cohesivness. That is, the opening, for example, is much faster then the following episode or parts of the development. And some of the ritardandos and sotto tempo places are too sudden. It's sort of patchy, in the outcome. And the brilliant parts are almost too flashy, at times, for me. But then I could be your grandfather and it's only normal that my conception is slower than yours. When I did the course with Kempff, I really didn't get certain things he did and said. But with time I really appreciated the different outlook he had on Beethoven. Very personal, and yet, at the same time, very very Beethoven, if you get what I mean. There are wonderful moments in this movement. Can't wait to hear the second!
