In 1957 Kaprow went on a mushroom hunt with artist, composer and founder member of the Fluxus group George Brecht and John Cage. Struggling with some of the sound elements in his own works (which he called action collages), Kaprow asked Cage’s advice. Cage invited him along to his composition class at the New School for Social Research in New York and, fascinated by what he heard about recording, editing and looping tape, Kaprow asked if he could attend regularly. Cage’s weekly homework was to create a piece of work and in response Kaprow began to create full-scale events that he called happenings.
