Generally regarded as one of Sabbath's worst albums, I nevertheless must admit that it, along with No Sleep 'Til Hammersmith by Motorhead, is responsible for most of my tinnitus, 30 years in heavy industry notwithstanding. The lyrics are mostly juvenile, the album art is atrocious, the lineup disintegrated after one world tour, yet for a spotty 15 year old kid in Newfoundland with his face buried in his bedroom carpet, with his detachable ghettoblaster speakers turned into his ears as ill-advised 20watt headphones, it was magic. Gillan and Sabbath. It couldn't last. And it didn't. Some suggest it was the inspiration for "This Is Spinal Tap." Whenever I get the urge to listen. the neighbours listen as well.
