Query: A Classic Introduction

Not only is this a great introduction for someone who doesn't know his or her way around this subject, but it offers more experienced listeners and readers Nyman's own sensitive, and (to my mind) highly accurate, takes on what Cage, Feldman, Brown, Cardew, LaMonte Young and others were up to back in the pre-revolutionary 50's and the revolutionary 60's and 70's. This is a snapshot, if you will, of many of the giants fully formed, and some, like Gavin Bryars, in the larval stages of their genius, so it makes for a fascinating read. Nyman's prose is pellucid, and his explanations cogent. My dream is that Michael Nyman will someday return to update this book and offer some insights on the new, strange paths, experimental music has taken in the age of the personal computer, robotics and the Internet.
