Sabbath Bloody Sabbath

Sabbath Bloody Sabbath is the fifth studio album by the English heavy metal band Black Sabbath, released on 30 November 1973. It was produced by the band and recorded at Morgan Studios in London in September 1973. The writing process for the album, which began in Los Angeles, California, was initially hampered in part by the band's substance abuse and fatigue following its 1972–1973 world tour in support of their previous album, Vol. 4. In an effort to get past their writers' block, the band relocated to Clearwell Castle in the Forest of Dean, Gloucestershire, England, where guitarist Tony Iommi conceived the main riff of what became the album's title track and lead single.

The album represented a stylistic leap forward for the band, incorporating synthesizers, strings, and keyboards into their normal heavy metal sound, in addition to other experiments by the band that ultimately would not end up on the album. For the first time in the band's career, Sabbath Bloody Sabbath received positive commercial and critical reception, later becoming Sabbath's fifth straight album to be certified platinum in the United States. The album continues to receive acclaim, both from critics and musicians.
