Machine Head, that's who!  The band hit up Green Day's Jingletown Studios in Oakland, California to work on their as-of-yet untitled seventh studio recording.  Word right now is that the drum tracks are all set and the album should be able to hit the shelves later this year.

Here's a sneak peak inside the studio courtesy of photographer, Scott "Captain" Kirkeeng.
