HPSCHD, a collaboration between John Cage and Lejaren Hiller was first performed on May 16, 1969 at the University of Illinois at Urbana-Champaign, called for seven harpsichords playing randomly-processed music by Mozart and other composers, 51 tapes of computer-generated sounds, approximately 5,000 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.

Composed in 1964, Ben Johnston's String Quartet No. 2 continues Johnston's brilliant compositions which utilize different tuning systems. Hearers of classics originally played in just intonation (pre-even-tempered tuning) would experience modulations within a piece as radical changes that added depth to the music subsequently lost with the adoption of even-temperament of modern times.

a continuación un texto extraído del libro "Electronic and Experimental Music 3r ed." de Thom Holmes :

" Another performance that must go down in history as one of the most complex multimedia events ever staged occurred in 1969 at the University of Illinois. John Cage and Lejaren Hiller teamed up to present a joint composition called HPSCHD. Using a computer-derived extrapolation of the I Ching developed for Cage, the two assembled 51 sound tapes generated by computer and combined them in a live setting with the activities of seven harpsichordists. The work was presented in a sports arena, with the electronic sounds amplified by 51 individual speakers mounted along the ceiling. Seven additional speakers were also used to amplify the harpsichords. In addition, 52 slide
projectors provided streams of unrelated imagery, which was projected onto a large hanging screen measuring 100 feet by 160 feet as well as a semicircular screen that ran 340 feet around the inside rim of the ceiling. For five hours, hundreds of people sat in the bleachers and milled around on the main floor of the arena immersed in this sensory bath. It was big and absorbing and live. The commercial recording of HPSCHD released by Nonesuch Records (H-71224) in 1969 included a computer printout (individualized for each copy of the record) with a randomly generated set of instructions for controlling the volume, treble, and bass knobs on one’s stereo while listening to the music. Each printout was individually numbered. Mine happens to be “Output Sheet No. 374.” "
