Harmonix has announced that Green Day will be coming exclusively Rock Band, with the first selection of DLC becoming available next month. It"s not their work from the "90s, or "American Idiot" for that matter, but it"s a start.

The first set of DLC will be a three-pack consisting of the songs "21 Guns," "Know Your Enemy" and "East Jesus Nowhere." They"re all from 21st Century Breakdown, the latest Green Day album, which was released on May 15.

Word that Green Day would be coming to Rock Band arrived on June 8, when vocalist Billie Joe Armstrong told a crowd at KROQ"s Breakfast with Green Day, "Yeah. We"re doing a whole Green Day Rock Band, uh," upon which he was cut off by cheering.
