Black Sabbath - Master Of Reality (Vinyl/Record)

Black Sabbath are an English rock band formed in Birmingham in 1968 by guitarist Tony Iommi, drummer Bill Ward, bassist Geezer Butler, and vocalist Ozzy Osbourne. They are cited as pioneers of heavy metal music; the band helped define the genre with their first three albums Black Sabbath, Paranoid, and Master of Reality. In the 1980s and 1990s, the band underwent line-up changes, though since 1997 it has settled with the original band.

Master of Reality is the third studio album by English heavy metal band Black Sabbath, released in the United Kingdom on 6 August 1971 by Vertigo Records. It is regarded by some critics as the foundation of doom metal, stoner rock, and sludge metal. Produced by Rodger Bain, who also produced the band's prior two albums, Master of Reality was recorded at Island Studios in London from February to April 1971. Guitarist Tony Iommi and bassist Geezer Butler down-tuned their instruments during the production, achieving what Iommi called a "bigger, heavier sound".
