Green Day have posted another studio update as they work on their follow-up to 2009's 21st Century Breakdown. This update comes as a video from the band, complete with clips from the studio and some brief riffage from a new track being recorded.

The band has been writing new material since at least June 2011, and several new songs have surfaced in Green Day's sets over the past year, including "Carpe Diem" and "Stray Heart."
