Black Sabbath is an English rock band, formed in Aston, Birmingham in 1969, by Ozzy Osbourne (lead vocals), Tony Iommi (guitar), Geezer Butler (bass guitar), and Bill Ward (drums). The band has since experienced multiple line-up changes, with Tony Iommi the only constant presence in the band through the years. Originally formed in 1968 as a heavy blues rock band named Earth and renamed Black Sabbath in 1969, the band began incorporating occult and horror-inspired lyrics with tuned-down guitars and achieving multiple platinum records in the 1970s. Despite an association with occult and horror themes, Black Sabbath also composed songs dealing with social instability, political corruption, the dangers of drug abuse and apocalyptic prophesies of the horrors of war. Black Sabbath are cited as pioneers of heavy metal. The band helped define the genre with releases such as quadruple-platinum Paranoid, released in 1970.
