Before the Second World War, American composers went to Europe. That was the way of the ‘boulangerie’, the group including Aaron Copland who studied with Nadia Boulanger in Paris. After the war, though, they began to take seriously Charles Ives’s declaration that ‘we have listened too long to the courtly muses of Europe.’ They started taking liberties. In Music 109, his winsome new book on the postwar American avant-garde, Alvin Lucier writes of his first encounter with the music of John Cage in Venice in 1960. David Tudor played the underside of a piano while Cage, Merce Cunningham and Carolyn Brown danced round the theatre reading instructions for actions out loud from cue cards. Cage tuned a radio to a broadcast of the pope pleading for world peace. At the end of the concert a courtly-looking gent strode angrily down the aisle, hit the piano with his cane and proclaimed: ‘Now I am a composer!’
