Sabbath Bloody Sabbath | Vibepedia

The album was produced by the band and recorded at Morgan Studios in London. The writing process was initially hindered by the band's substance abuse and fatigue, but a change of scenery to Clearwell Castle in Gloucestershire, England, helped to spark creativity. Tony Iommi was the primary songwriter and guitarist for the album, and Ozzy Osbourne was the lead vocalist and a key contributor to the songwriting process. Iron Maiden, Metallica, Judas Priest, and Slayer have all cited Black Sabbath as a major influence.
