This is a tremendously informative book. Densly packed with info, and a fascinating read. My only complaint is that, since chapters were contributed by different writers, there's no style that really permeates the book. The chapter on Techno, for example, does a great job at contextualizing the Detroit sound, pointing out the influences that led to the evolution of techno, from a musical perspective, as well as from a social and even economic perspective. Unfortunately not all chapters are written the same way. The chapter on House, for example, is a bit dizzying for readers unfamiliar with the sounds and beats being described. But nevertheless... READ IT. (And Dance to it, more importantly!)
