If you are a Van Halen junkie this is a book that covers some details you probably didn't read anywhere else since the author of the book did extensive interviews with people who knew the guys in Van Halen. He really put a lot of work into getting some first hand information and did a good job putting it all down into a book. Dave was a straight laced kid under his strict Jewish mom but when his parents divorced and Dave's mom was no longer hovering over him he broke loose and became Diamond Dave. Eddie was not much of a party animal in high school. His friends said basically all the guy did was play guitar so no wonder Eddie got so good at it. Interesting insights like this fill the book.
