This book by Bill Bruford is very hard to review. As a scholarly study, it deserves 5 stars. Most likely, it would also be useful for musicians in a band context. I am a big fan of music and Bill Bruford. I understand many things that the typical reader might not. However, the book was hard to get through and didn't really hold my interest. I read the Introduction and Appendix completely but only skimmed the rest of the book.
So... well done, but not for me. For most people, I would (highly) recommend "Bill Bruford The Autobiography" instead.
