Best Piano Music for Relaxation & Focus - Calming Classical & Modern Piano Songs for Studying, Meditation, and Sleep

This CD comes from a Deutsche Grammaphon recording of 1975, with Maurizio Pollini at the piano. He, of course is a fine pianist, but Schoenberg's music is not to everyone's taste. Some of it is not bad, but it does take intense concentration to gain from what Schoenberg is trying to do. I admit that struggle with it a bit.
