Query: Disapointing; you can safely skip this one

Other reviewers have already dinged this book for its inacuracies, lack of original research, and opinionated conjecture. I agree whole-heartedly. I found the prose to be rambling, and the overall treatment to be superficial. The book focuses almost exclusively on Zappa the man, with very little about the music. In other words, don't expect to learn any new "conceptual continuity" clues. Even then. I knew most of what was in this already, which was probably the biggest let-down. I can't recommend this: it's the type of "rock journalism" Zappa himself railed against.
