With creative frustrations heightened by rocketing substance abuse and fatigue, Sabbath’s future didn’t look quite as secure as it once did. Relocating back to London after the initial sessions for album number five proved unfruitful in LA, they ended up writing a psychedelic masterpiece. “The lyrics to Sabbath Bloody Sabbath were about the Sabbath experience: the ups and downs, the good times and bad times, the rip-offs, the business side of it all,” reflected Butler in the notes for their 2004 Black Box collection. “[The line] ‘bog blast all of you’ was directed at the critics, the record business in general, the lawyers, accountants, management, and everyone who was trying to cash in on us. It was a backs-to-the-wall rant at everyone.”
