Good book that present 40 legends of music, mostly from rock, pop, hip hop, on a vast time period. Beautiful, easy to goes through, well organized, it may be an interesting book for the young ones who are interest in music and want to discover old/classic bands. Not very fit for adult, unless you have no musical references at all, because everybody knows those artist and the fact about them are too basic for adult liking. But like I said good introduction book for kids!
