After much speculation, the original four members of BLACK SABBATH--Ozzy Osbourne (vocals), Tony Iommi (guitar), Geezer Butler (bass) and Bill Ward (drums)–have reunited to record their first new studio album in 33 years with producer Rick Rubin (seven-time Grammy winner, two of those as Producer of the Year) and to embark on a massive world tour in 2012.

Osbourne, Iommi, Butler and Ward as well as Rubin all gathered today on 11/11/11 to announce the news at a Los Angeles press conference at the legendary club, the Whisky A Go-Go, the site of the groundbreaking and influential band’s first L.A. concert exactly 41 years ago (Nov 11, 1970). The event was hosted by the revered musical and spoken word artist Henry Rollins who has said that, “Any band worth their weight in napalm wishes they had written ‘War Pigs.’”

Selling over 70 million albums together, the Grammy-winning, Rock and Roll Hall of Fame inductees have signed a new record deal worldwide with Vertigo and Vertigo/Universal Republic in the U.S., the band’s original label. BLACK SABBATH is now in the studio recording the as-yet-untitled new album for release in the fall of 2012 (exact date TBA). It will mark their ninth studio album together and their first since 1978’s Never Say Die!

Next summer, BLACK SABBATH will headline the mammoth multi-day UK Download Festival in the U.K. on June 10. The new album will then be supported with a worldwide headline arena tour (dates TBA).

BLACK SABBATH also announced today the launch of www.blacksabbath.com, the first-ever official BLACK SABBATH website for all authorized BLACK SABBATH news. In addition, the band’s online presence will also be supported by social media via Facebook and Twitter–again, marking the band’s first-ever foray into the social media world.
