With the acceptance of rock music as a valid art form there has been a proliferation of boring and pretentious literature on the subject. Thank god this book isn't one of them. In fact, Derogatis is able to fuse good writing with the enjoyment of rock music for what it is: a primal illiterate art form. In this particular case, Derogatis presents an overview of a type of rock 'n' roll which is about sensory overload, "unreality", and FUN!!! This book covers everything in "head" music from the Beatles, Beach Boys, to Kraftwerk, Can, and the Flaming Lips. All in pop historical context. Get it.
