One of a series of experimental texts in which Cage tries "to find a way of writing which comes from ideas, is not about them, but which produces them," he attempts in X to create looser structures in both life and art, to free "my writing from my intentions.""The New Grove Dictionary flatly states about Cage: 'He has had a greater impact on world music than any other American composer in the 20th century.' An observation that even Cage's most violent detractors would probably not dispute." -- Peter G. Davis, New York Magazine
