"In this book nine highly articulate members of the most interesting avant-garde movement in art discuss their purposes and processes : John Cage, Ann Halprin, Robert Rauschenberg, Allan Kaprow, Claes Oldenburg, Ken Dewey, La Monte Young, Robert Whitman, and USCO (the name of an artists' collective). Two lucid and stimulating essays by Richard Kostelanetz provide a unique interpretation of the new theatre in terms of its historical, social, and aesthetic meaning. Here are path-breaking ideas about the future of art and society in an age of absolute imaginative freedom and technology of unprecedented sophistication." -- from interior flap.
