Master of Reality is the third album by the British heavy metal band Black Sabbath, originally released in 1971 and now available on 180 Gram Vinyl. Master of Reality was certified double platinum after having sold over 2 million copies. Black Sabbath-the Black Sabbath, the original lineup of Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward, four childhood friends from the north of England-grew out of the U.K's late-60s blues/hard rock scene, which also included Led Zeppelin, Cream, Blue Cheer, and other greats. Sabbath's sweeping and masterful metamorphosis away from that tradition spawned heavy metal music, inventing the template for everything that would follow. with crushing rhythms, torpedo riffs, haunting songs, and Ozzy's other-worldly vocals, the band conjured a dark, menacing, and resonant sound that reverberates still.
