Today's composer of the day is Cornelius Cardew.
English serialist turned experimental free-improvisor turned Socialist post-Romantic composer.
He was once Stockhausen's whipping boy. Then, he discovered John Cage and David Tudor. Cardew's most famous work, Treatise, is a 193-page graphic score, which was recorded by numerous ensembles, including Sonic Youth. He then wrote a lengthy article entitled, "Stockhausen Serves Imperialism." It's a fun read.
Finally, he was run over by a car. He died.
You should listen to his music.
