Green Day

Details about punk pop luminary Green Day's next full-length have been few and far between since we last checked in with the boys. But according to ex-Garbage frontwoman Shirley Manson -- and confirmed in the video below! -- the band is hard at work on the follow-up to 2004's American Idiot -- and they've recruited a familiar producer to man the soundboard.

In a sit-down on Last Call with Carson Daly to promote her acting role in TV's Terminator: The Sarah Connor Chronicles, Manson dropped a juicy tidbit when asked about the status of a new Garbage record. "I don't know, to be honest," Manson explained. "We're sort of doing our different things. I'm doing the TV show, Butch [Vig] is producing Green Day, so he's busy, we'll see." [Via MTV.com]

On the heels of Manson's comments -- as well as a few other recent rumors -- the band have posted a YouTube video showing frontman Billie Joe Armstrong and Vig in the studio hard at work on the trio's forthcoming album. Below, check out the footage -- with explicit finger gestures courtesy of Vig -- featuring Armstrong strumming away at his guitar as instrumental tracks from two new songs play in the background.
