“HPSCHD, a collaboration between John Cage and Lejaren Hiller, first performed on May 16, 1969 at the University of Illinois at Urbana-Champaign, called for 7 harpsichords playing randomly-processed music by Mozart and other composers, 51 tapes of computer-generated sounds, approximately 5000 slides of abstract designs and space exploration, and several films, all of which were performed or presented simultaneously in an asynchronous and exuberant anarchy of activity. HPSCHD was the ultimate multimedia experience” (zit. nach http://emfinstitute.emf.org/exhibits/hpschd.html).
