Tom Hartley suggests listening to the surgingly satanic Webern (six letters in his name) 6 Stücke or Pieces (six again) Opus 6. The Levine / Berlin (6/6) recording is unfortunately of print, in which case there is no choice but Pierre Boulez / Berlin (6/6/6). Search iTunes for "Webern Boulez op. 6," and try no. 4.
