Black Sabbath Gathered in Their Masses

Heaven and Hell is the ninth studio album by English rock band Black Sabbath, released on 25 April 1980. It is the first Black Sabbath album to feature vocalist Ronnie James Dio, who replaced original vocalist Ozzy Osbourne in 1979. Produced by Martin Birch, the album was a commercial success, particularly in the United States, where it reached number 28 on the Billboard 200 chart, and was certified platinum for 1 million sales in the United States alone. One of Sabbath's finest records!

Master of Reality is the third studio album by English rock band Black Sabbath, released on 21 July 1971. It is widely regarded as the foundation of doom metal, stoner rock, and sludge metal. It was certified double platinum after having sold over 2 million copies. Master of Reality was Black Sabbath's first and only top 10 album in the US until 13, forty-two years later. If Paranoid has more widely known songs, the suffocating and oppressive Master of Reality was the Sabbath record that die-hard metalheads took most closely to heart.
