Cornelius Cardew (1936-81) developed a philosophy of experimental notation and indeterminacy that influenced art music throughout the world. He was a deeply moral thinker, engaged in a constant struggle for truth in art, life, the political world, and himself. In face of all criticism and mockery, he stood with his personal, political and aesthetic beliefs against British musical conservatism, the avant-garde establishment, and finally, the experimentalism he himself had created. - mersenne from Bookmarklet
