Black Sabbath have organized a press conference for Friday, November 11.

All four original members of the band – Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward – will be in attendance at the announcement, to be held at the Whisky A Go-Go in Los Angeles.

The date is not an accident. November 11 isn't just "National Metal Day" (11-11-11), it's also an important anniversary for Sabbath. The date marks the legends' first U.S. show, which took place November 11, 1970 at – wait for it – the Whisky A Go-Go.

Henry Rollins will host the event, during which the band members are expected to announce a reunion tour and, possibly, a new album.
