Green Day dawns on Rock Band July 7

Green Day lead singer Billie Joe Armstrong has been neither shy nor overly descriptive about his band's upcoming debut in Rock Band. So while it's been known that the punk rockers' music would be appearing in the rhythm game franchise, there's been some question as to whether it would be in the form of downloadable tracks, a full album, or a stand-alone retail product, such as The Beatles: Rock Band or AC/DC Live: Rock Band Track Pack.

The answer might be "all of the above." MTV Games today confirmed that Green Day's music will be appearing in Rock Band starting next month. While the company only announced a July 7 launch for three songs from the band's latest album, 21st Century Breakdown, it noted that, "Additional Green Day songs and projects will be announced at a later date."

The three-song pack will include "21 Guns," "Know Your Enemy" (seen below), and "East Jesus Nowhere." MTV Games did not specify if the game's downloadable storefronts for the Xbox 360, PlayStation 3, and Wii would all be receiving the content that week.
