I-IV. The Charles Elliot Norton Lectures, 1988-1989

452 pp. plus two audiocassettes. Illustrated with 15 different chance-determined prints from a single negative of the first autograph page of Cage’s “Sixteen Dances” (1951). SIGNED BY JOHN CAGE. Text includes transcripts of question-and-answer session after each lecture (edited by Cage); one audiocassette records Cage delivering a lecture; the other, a selection from the question-and-answer sessions. The lectures were more like performances, their content generated by chance based on computerized I-Ching operations. Box about fine.
