Heavy metal's founding forgers Black Sabbath announced the details of their long-anticipated reunion today at the Whisky A Go Go, the legendary dive where they played in Los Angeles for the first time more than 40 years ago.

The original band members will record a new studio album — their first with Ozzy Osbourne since 1978 — with producer Rick Rubin; it's due in fall 2012 via Vertigo/Universal.

Osbourne, guitarist Tony Iommi, bassist Geezer Butler, and drummer Bill Ward will support the disc with a large-scale worldwide tour including a headlining slot at the Download Festival on June 12, 2012.
