Harmonix and MTV Games today announced that three exclusive tracks from multi-platinum, Grammy® Award-winners Green Day, as well as eight songs from artists performing at the premiere of the RockStar Energy Drink Mayhem Festival, will be added to the Rock Band® Music Store of downloadable content next week for the Xbox 360® video game and entertainment system from Microsoft, PLAYSTATION®3 computer entertainment system and Wii^TM system.

The Green Day tracks available next week are the first in an exclusive partnership between MTV Games' Harmonix and Warner Music Group's Green Day to bring the band's songs to the Rock Band platform as downloadable content. These first songs, "21 Guns", "Know Your Enemy" and "East Jesus Nowhere," are from the band's latest album, 21st Century Breakdown.

Selling nearly 50 million records worldwide, Green Day has won critical acclaim and numerous accolades, including three Grammy Awards for Best Alternative Album for Dookie, Best Rock Album for American Idiot and Record of the Year for their smash hit "Boulevard of Broken Dreams." Green Day recently released their eighth studio album, 21st Century Breakdown, on Warner Music Group's Reprise Records. The album debuted at No. 1 on the Billboard Top 200 chart, as well as on the Rock, Active Rock and Alternative charts, fueled by the Alternative radio No. 1 single "Know Your Enemy." 21st Century Breakdown, which Rolling Stone has called "a rock opera in which the rock always comes first," is also a hit around the world, topping the charts in 24 countries, including the United Kingdom, Canada and Japan.

Eight songs from artists performing at the RockStar Energy Drink Mayhem Festival, including Behemoth, Cannibal Corpse, Marilyn Manson and Slayer, will also be available for download next week in the Rock Band Music Store. The RockStar Energy Drink Mayhem Festival is a new summer touring metal and rock festival in the United States during July and August, assembled by Vans Warped Tour founder Kevin Lyman.
