I knew right away that the book was worthless when the New York Dolls had one of the top ten "heavy metal" albums of all time. The NY Dolls are a GREAT -one of the GREATEST- punk rock/glam bands of all time, but they're simply not heavy metal. They, like the Stooges, Ramones, et al. are playing a million different variations of Chuck Berry only faster and more raw. It's got power, angst and everything else, but it IS NOT METAL. If someone of consequence, say a mainstream journalist uses this book as a reference (never happens...) there will be a lot of articles confusing metal with punk rock and all the rest of rock and roll. Granted, Led Zepplin IS metal (right?) and rightly deserve the praise they get in this book but Black Sabbath is THE band that got it all started. Eddy brushes off Black Sabbath like they were of minor significance. He also dismisses Iron Maiden, Judas Priest, all the death metal, speed metal, etc. that's been of tremendous significance in clearly defining what "heavy metal" is. It's not even a funny joke that P-Funk and the Osmonds are included in the book. What's the point in calling these bands/people heavy metal? I mean, rock and roll is a huge tent, but some parts of the tent simply do not mix and it is unfair to have included non-metal bands in this book. It is pointless to purchase it as it is of no value except as a novelty - which means "save your money."
