Welcome back, This Week in Rock Band brings you all the tracks, packs or albums available for your favorite band simulator this Thursday (groupies not included but highly recommended).

There’s a new tour in town and its name is the RockStar Energy Drink Mayhem Festival.  Okay, so it is more a festival than a tour, but facts are facts:  this one kicks the Vans Warped Tour’s ass from here to next Thursday and here’s why: it’s a metal and rock festival.

Six tracks from RockStar Energy Drink Mayhem Festival performers such as Slayer, Cannibal Corpse and Marilyn Manson are contending for your hard earned dollars, pounds or euros against an arguably far more popular threesome.  Green Day is coming to town.

Armed with three tracks from their latest studio album, 21st Century Breakdown, Green Day inked an exclusive partnership with Harmonix to bring the band’s songs to Rock Band as DLC.

That’s right Heroes, drop your Guitars and join the Band.  Rock Band.
