Zappa was always a kingmaker. If he were a whore, he would have been the greatest and richest corporate rock producer in the world. But, alas, Frank wasn’t in it for the money. Still, whenever he sneezed, people listened. Zappa thought Sabbath were great, while early critics panned them. From an interview with Geezer Butler:
WW: Speaking of prejudice, during those early years, Sabbath got some of the worst reviews ever. Critics seemed to hate the band – but a number of years later, when Sabbath proved to be so influential, they completely flip-flopped. What was the moment where you first saw that sea change?
GB: I think some of them got an inkling when Frank Zappa did this interview in one of the big English music papers. They were asking him what music he was listening to at the time, and he said, “Black Sabbath.” And at the time, Frank Zappa was really well thought of critically. And I thought he was joking! (Laughs.) But he thought “Supernaut” [from 1972’s Black Sabbath, Vol. 4] was the best riff he’d ever heard. And a lot of critics went, “Well, if Zappa likes Black Sabbath, maybe we should give them another listen.” So that turned some of the people.
Oh wait, that’s Barry Manilow!
