"Black Sabbath", "Paranoid", "Master of Reality", "Volume 4", "Sabbath Bloody Sabbath", and "Sabotage". Those are the first six, and for a long time the only true Black Sabbath albums ever released. With all respect to Dio, Zakk Wylde was right, those were the only true Black Sabbath albums...and even then, he said it was Ozzy era, but "Technical Ecstasy" and "Never Say Die", while not as bad as some fans will make them out to be, were even really not true Sabbath albums as far as what I think of when I think of Black Sabbath. It's not just me though, there's a number of other fans of Black Sabbath that will agree with that. However, the next true Black Sabbath album came from an unlikely source. By that, I mean that it didn't come from Black Sabbath.
