Who produced Black Sabbath's final studio album, 13?

Black Sabbath’s final studio album, 13, was produced by Rick Rubin.

The album reunited Ozzy Osbourne, Tony Iommi and Geezer Butler for their first full studio project together since the 1970s. Although work began as early as 2001, recording was delayed for years by the members’ separate projects and Osbourne’s solo career. The album was finally recorded mainly in 2012 and released in 2013.

Rick Rubin was also involved in the abandoned early-2000s sessions, making him a continuing presence in the album’s long development. Brad Wilk of Rage Against the Machine played drums during the completed recording sessions after original drummer Bill Ward did not participate.

A common mix-up is confusing Rubin’s production role with engineering or mixing credits. Greg Fidelman engineered the album, while Andrew Scheps handled the mix. 13 was Black Sabbath’s nineteenth and final studio album, and its single “God Is Dead?” won the 2014 Grammy Award for Best Metal Performance.
