This book is exactly what you want it to be, very descriptive, thought-provoking, detailed and explains all the ups and downs of being in a band and being in the band Black Sabbath. Geezer writes in such a way that he does not leave the reader wondering about anything but still tells his story as the gentleman that he is. Having been a fan since the late 70s, I learned more about the band and all of the lineup changes that I was not aware of.
