Green Day has begun work on a new album. In a series of tweets, frontman Billie Joe Armstrong talked a bit about the process thus far:

"Ok here's the scoop. GD has been jamming new songs everyday. There's a ton of new songs. The direction is fresh and hi energy. Feels great … I don't want to give away too much but just know that me mike tre and Jason are collaborating and having the best time playing music. And that's not bullshit!!"

The wildly popular band released 21st Century Breakdown in 2009.
