Black Sabbath is expected to reuinite on 11/11/11.

Black Sabbath will host a press conference tomorrow in LA, where it is widely believed they will announce a reunion tour, and possibly a new album.

The band has been rehearsing in Ozzy Osbourne’s California home, and while all of the members have taken the “cautiously optimistic” stance in interviews, it’s likely that optimism will be fulfilled tomorrow. On 11/11/11, at 11:11am, the four original members of Black Sabbath will hold a press conference at Whisky A Go Go in Hollywood, CA – which, not so coincidentally, hosted Black Sabbath’s first show 41 years ago to the day.

Between the rehearsals and constant reunion-related hints in the recent past, we think it’s safe to get excited, what with the bombast of that countdown meter on Black Sabbath’s official site and all. We’ll be back on the story tomorrow once the news makes itself official.
