The extent to which Cornelius Cardew has been a central figure and a force for new ideas in music forms the backbone to this book. Cardew's diverse body of work and activity is here given coherence by their sharing in the values and principles that underpinned the composer's world view. The apparently disparate and contradictory episodes of Cardew's career are shown to be fused by a cohesive 'Cardew aesthetic' that permeates the man, his politics and his music.
