It is not unknown to me but for me there are a bit too less variations in this music, it is very "sleepy". But I like a somewhat similar CD called "Spielerei - Wichman And Other Pieces". Artist "Spielerei" sounds somewhat similar to this but this "Wichman" CD is better, especially the "The Wichman Concert" parts on it. Not on youtube but listenable on Saiko Sounds.
