A collection of letters and writings by avant-garde composer John Cage. "These papers and addresses mirror his major concerns. Here are statements of his views on experimental music: Composition by chance operations, indeterminacy of performance, the use of electronic sound, the value of ambient noise. Here are the formalized lectures- as off-beat in structure as they often are in idea- that have caused him to be regarded as a prophet by some and as a poseur by others." -- from dust-jacket end flaps.
