Query: not good

I did not read this book as a true fan should never look into this book. If you want to know the history of slipknot, then buy the book that was actually put out by roadrunner and authorized by the band. One reason that they started putting on the mask was to freak you out, why take away that by wanting to know what they look like. Plus, if you are a fan, then you already know what they look like from some of their side projects. Also they wear mask to make sure that punk butt kids don't bother their familys and them when they are out and about. Please, respect the band and respect their familys. Don't buy this book and be a poser.
