Query: A Very Detailed Book, Well worth the purchase

This book has a lot of interesting facts about the band, "KoRn". I just bought it a couple nights ago and I couldn't put it down. The pictures were great, a lot of cool pictures of Jon. Each band member was explained specifically. It tells about how the band formed and what they had to do to become what they are now, and etc. It's well worth 15 dollars, buy it.
