Originally published in 1974, Stockhausen Serves Imperialism is a collection of essays by the English composer Cornelius Cardew that provides a Marxist critique of two of the more revered avant-garde composers of the post-war era: Karlheinz Stockhausen and John Cage. A former assistant to Stockhausen and a champion of Cage in England, Cardew provides a cutting rebuke of the composers’ works and ideological positions, which he saw as reinforcing an imperialist order rather than spotlighting and serving the struggles of the working class.
