Black Sabbath Bassist Geezer Butler: ‘Never Say Never’ Concerning ’13’ Album Follow-Up

Black Sabbath have mostly received positive word-of-mouth for '13,' their first new album in 35 years, which begs the question of whether or not we'll see more original music from the metal icons down the road.

Bassist Geezer Butler tells Billboard concerning their future work, "Well, I guess you should never say never. It could be [our final album], though. We'll see how this album goes. We'll see what happens."

Frontman Ozzy Osbourne added, "Let's put it this way, it's taken us 35 years to do this one. So if there's gonna be [another] album, there's gonna be another album, but I don't want to say if there's going to be a follow-up. I wouldn't mind doing another Sabbath album with them, though."

The band has already yielded a radio hit with the rapidly rising single 'God Is Dead?,' though the '13' disc as a whole is more album-friendly with much of the material clocking in at over five minutes and some songs exceeding the eight-minute mark.

The band recorded '13' with acclaimed producer Rick Rubin behind the boards and Rage Against the Machine's Brad Wilk handling the drums in place of estranged skinbeater Bill Ward.

The '13' album arrives in stores June 11.
