Satisfyingly straightforward. As a fumbling bassist about a decade younger than Geezer, from a similar ethnic and religious background, his explorations of how his early faith, later skepticism, precocious vegetarianism -- long before it was fashionable-- and the expected details of life with Ozzy, Tony, Bill and seemingly dozens of bandmates all kept my interest. I admit not being a huge Black Sabbath fan who knows much about them past their first four groundbreaking albums, so a lot of the chronicles about their gigs, splits, reunions, and splinter lineups might be more relevant to the devoted followers of everything that Geezer has been associated with for decades in the studio, on stage, and on the road.
I would have liked the nitty-gritty about which kinds of basses he favored out of the over eighty he owns, and a deeper dive into intricacies of crafting the Sabbath sound, but this may be due to my own predilections for production techniques and bass processing and manipulation. He does provide solid information about his lyrics, and corrects the misreading and distortion of how his messages. He shows how what Sabbath was all about comes from a moral worldview (at its best), and also the damage drugs, drink, and debauchery created for its many members.
