Sabbath Bloody Sabbath is the fifth studio album by English heavy metal band Black Sabbath, released in 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 their 1972–1973 world tour in support of their previous album, Vol. 4. The band then 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.

Black Sabbath were 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 often 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 (1971). Following Osbourne's departure in 1979, the band underwent multiple line-up changes, with Iommi being the only constant member throughout their history.
