Heaven and Hell is the ninth studio album by English rock band Black Sabbath, released on April 25, 1980. It is the first Black Sabbath album with vocalist Ronnie James Dio, who replaced Ozzy Osbourne in 1979. Produced by Martin Birch, the album was a commercial success, especially 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. The arrival of Dio marked a new period in Black Sabbath's creativity, with classic heavy metal replacing the doom that was well noticed on Ozzy's releases. The album is considered one of the best in the band's history and contains everything: fast tracks, ballads, aggression and calmness, melody and heaviness.
