"I met him Cummingham around 1953 after a performance I saw. He was teaching and making dances for his company and was already working with John Cage. What interested me initially wasn't just the movement but also the music he worked with, which was unfamiliar to me.. .Later Bob Rauschenberg had been doing sets and costumes for the Cunningham Company.. .I can't say exactly how, but for a period of time, Cage, Cunningham, Rauschenberg, and I saw each other frequently and exchanged ideas."
