It is difficult to describe how disappointing this book is or why the information is presented in such a repititious way. It appears to be a blend of interviews from many previous sources (including the author's) and this makes for a confusing read. When answers to specific questions about the performances of Cage's music include different recollections from various interviews within the same paragraph, you end up feeling like your reading a term paper rather than an insightful treatise. After 100 pages of this confusion and constant repetition, I gave up. I know Cage is compelling but you would not know it from this book.
