I've re-uploaded this (http://www.youtube.com/watch?v=Klh9GiWMc9U) because the new time limit for videos allowed me to combine the Toccata, Adagio,...
The only part that interests me is from 3.08 onwards. Incredibly sad and genius. Busoni has a successful transcription of this for piano, but where the last part of the adagio changes character from sad to aggressive and triumphing - interesting!
This version of the prelude was rocky as hell. I have to subscribe.
