funny, I listened to this yesterday (it's the first time I heard the piano version) and I absolutely loved it! I think I'll play it too, I borrowed the sheet music from the library today. If we both start today, boliver, we can compete about who finishes it first
I listened to Horowitz recording and then looked at the sheet music, and he obviously has made some changes in the music. Or are those someone elses changes? I really don't know. In"the castle" (don't remember the exact title), for instance, he skips half a page or something like that towards the end, where the main theme comes back. I don't remember all of the other changes, but it was one piece which started with a RH tremolo in the high register which he played different.
