Karlheinz Stockhausen died last week. I haven’t followed him on any of his recent ridiculous mystical turns, but his music of the late 50s and early 60s was and remains the finest of Cage-inspired symphonic music (among other things). Particularly, I think, the Gruppen für 3 Orchester.
YouTube has a couple of interesting clips, including an excerpt from the wacky Helicopter String Quartet, a nice materialist moment amid his late mysticism,
and the late 50s electronic piece Kontakte, which has an amazing (contemporary) video accompaniment. I like video artist’s insertion of the Pavement guitar part near the end. It shouldn’t, but it works.
Anyway, RIP Stockhausen.
