The founding members of Black Sabbath appeared in Los Angeles to make it official that their first album of new material since 1978 is coming next fall and that they're already gearing up for a tour, Billboard reported Friday.

Legendary producer Rick Rubin, who's collaborated with the Beastie Boys and the Red Hot Chili Peppers, will be on hand to master the recordings.

Black Sabbath's four members -- who made the announcement during a press conference at Whiskey a Go Go on the 41st anniversary of their debut there -- are also headlining England's Download Festival in June.

Frontman Ozzy Osbourne hinted in October that putting out new music with Black Sabbath was a very, very strong possibility.

Guitarist Tony Iommi revealed Monday that he, bassist Geezer Butler and drummer Bill Ward came to Osbourne's California home and had a jamming session with the Prince of Darkness this year for a bit of fun, and to see if we could all play.

Of the eight albums Osbourne cut with the other members of Black Sabbath before they parted ways with him over his excessive substance abuse, five have gone platinum and three have gone gold. Paranoid, Black Sabbath's sophomore effort, sold more than four million copies and includes signature tunes like Iron Man and War Pigs.
