The reunited BLACK SABBATH - guitarist Tony Iommi, singer Ozzy Osbourne, bassist Geezer Butler - look ahead to their headline performance at Download 2012, and discuss how they're looking to the future, including a new album, in the wake of guitarist Tony Iommi's successful treatment for cancer.

The trio also discuss the status of original drummer Bill Ward. Ozzy says "the door is still open. His requests were unreasonable. Nothing would've been better than to have him play."

Black Sabbath are currently working on their first studio album in thirty three years and first since 1978's Never Say Die! with producer Rick Rubin (SLAYER, METALLICA).

Speaking to NME in a new video interview, the band discussed the direction of the new material, the influence of Rick Rubin and their recent Download warm-up gig in Birmingham.

Commenting on the progress of the sessions, Osbourne said: "We've written about 15 songs so far, whether they'll get on an album [I don't know]… You just keep on writing. I was trying to [work out]: where would we be now musically if we'd have stayed together?

He added: "Next year - 2013 - is a good clue of what we'll call the album."

Meanwhile, bassist Geezer Butler revealed how Rubin had approached the writing sessions with the band, explaining: "He sat us down, put the first album on and said 'listen to this', imagine it's 1969, you've just done that, what would you do next?"
