"We're finished recording it," Geezer tells That Metal Show's Eddie Trunk. "Tony [Iommi]'s back in England putting down a couple of solos. Then we start mixing it in February, and it'll be out in June."

"The provisional title is '13', unless we can come up with something more constructive."

For the new project, Geezer continues his long-established role as principal lyricist for the band.
