Considering Ozzy Osbourne and Co. were being sued by their former management, the results of Sabbath's sixth studio album are pretty impressive. To the casual classic rock fan, the songs might not be all that memorable. Yet, "Symptom of the Universe" had a huge influence on the thrash metal genre, while "Megalomania" is more than 9 1/2 minutes of an almost prog-rock trip with some of Tony Iommi's most unheralded guitar work. Listeners can feel the band's collective aggression from start to finish.
