I've played drums since 1977, but the only time I ever even noticed owt Grohl played was on Killing Joke's Death and Resurrection Show. Nowt else he's done has ever stood out to me.
Anyhow, I will buy this book, obvs, but I'm not really surprised that it's called 'Beast' - publishers bigging up the rock pig hi jinks will get them a few sales over and above the ones to people who want to know how often Bonzo practiced the Purdie shuffle, etc.
