I bought this book about a year ago and have read it 4 times since. Despite being a huge, scolarly, intellectual work, it still manages to exite at just the same level as the music about which it speaks. Facts and ideas appear and disappear again only to resurface generations later in a different, often more potent and subversive context. Some of the ideas covered are self-evidently unworkable (as Marcus knows as well as his readers) but they still excite and energise the imagination through their sheer radicalism. Like the best Punk Music they prompt the reader to a paradoxical reaction: "I can't condone any of this intellectually, but I feel like fighting in the streets to defend it". Read it, and it will remind you how pitifully dull and conformist your life is. Obviously, you won't be manning barricades on the street, but your first reading of this towering work will blow your assumptions and preconceptions apart and regular helpings thereafter will keep your sense of intellectual radicalism alive, kicking and screaming "Destroy!!"
