Tony Iommi, who is knee-deep into recording Black's Sabbath's new album, 13, is already looking beyond that project to something new — a riff-based album with Queen guitarist Brian May. The idea behind the project, as reported by RollingStone.com this morning, is that fans would be able "build their own songs" around Iommi's and May's unused material.

In a recently posted video from last month's 2013 Winter NAMM Show, That Metal Show co-host Eddie Trunk -- who also roasted Dee Snider at Guitar World's Rock & Roll Roast -- interviewed Black Sabbath bassist Geezer Butler at the Samson/Zoom/Hartke booth.

Throughout the decades, Phish have made a habit of performing "out of the blue" covers during their fan-favorite New Year's Eve Shows. In the past, they've performed complete albums by The Beatles (the White Album) and Pink Floyd (Dark Side).

For the past few days, Black Sabbath have been posting regular studio updates on their Facebook page, keeping fans in the know as they record their new album. The latest update, posted Monday, confirmed that guitarist Tony Iommi was tracking more guitar parts (Check out the photo below). Before that, we found out bassist Geezer Butler was hard at work on the album.
