The original score is only a page long and would normally take just a minute or two to play, but at the top appears this instruction: “In order to play this motif 840 times, one would have to prepare oneself in advance, and in the utmost silence, through serious immobilities.” Cage took this sentence at face value, and, on September 9 and 10, 1963, at the Pocket Theatre in New York, he presented Vexations complete. A team of twelve pianists played from 6:00 p.m. until 12:40 p.m. the following day. The New York Times responded by sending a gang of eight critics to cover the event, one of whom ended up performing. In the audience for part of the time was Andy Warhol, who remembered the experience when he made an eight-hour film of the Empire State Building the following year.

      The venue was equipped with a time clock, which patrons punched on entering and leaving. Listeners were reimbursed five cents for each twenty minutes they spent in the hall. Those who saw the entire performance received a twenty-cent bonus. Karl Schenzer, an off-Broadway actor, was the only one to get a full refund, having sat in the hall for nearly nineteen hours. “I feel exhilarated, not at all tired,” Schenzer told the Times. “Time? What is time? In this music the dichotomy between various aspects of art forms dissolves.”

       Feldman

      It was after a New York Philharmonic performance of Anton Webern’s Symphony, on January 26, 1950, that John Cage met a six-foot-tall, nearly three-hundred-pound Jewish guy named Morton Feldman. Both men had walked out of Carnegie Hall early—according to Feldman, because they were dismayed by the hostile response that Webern’s music had inspired in Philharmonic listeners; according to Cage, because they wanted to avoid hearing Rachmaninov’s Symphonic Dances, which ended the program. When their paths crossed by the door, Feldman turned to Cage and asked, “Wasn’t that beautiful?” A lifelong friendship began.
