Sabbath Bloody Sabbath - Black Sabbath

Album #5 in Year #3. Great output both in quality and quantity. Wish they'd put out that kind (or any kind for that matter) of quantity now. Has some very experiemental stuff on it, has a more of a keyboard influence - but that might be because of the presence of Yes keyboardist Rick Wakeman on the album. Probably their best mix of material in the Ozzy era when you factor in both the power of the early stuff and the experimentation of the latter stuff.
