Earlier this week, Activision announced that Blizzard Entertainment's house band Level 70 Elite Tauren Chieftain would be lending its World of Warcraft-inspired "I am Murloc" as a free downloadable track in Guitar Hero III. Today, another parody band has stepped up to the mic for an on-the-house performance, this time for Guitar Hero rival Rock Band.

　　With Fox's The Rocker starring Rainn Wilson (The Office, Wheelman) out next month, MTV Games and Harmonix are offering a cut from the film's fictitious glam metal act Vesuvius as part of next week's downloadable content. "Promised Land" will be available as a free download for the Xbox 360 on July 1 and the PlayStation Network on July 3.

　　With the Motley Crue-headlined Cruefest kicking off next week, MTV Games will be paying tribute to the tour with the next regularly scheduled DLC update. Included as part of the Cruefest Pack will be Motely Crue's "Down at the Whiskey," Papa Roach's "Time Is Running Out," and Trapt's "Who's Going Home With You Tonight." The Cruefest Pack can be purchased for $2.99 (240 Microsoft points), or each song can be picked up individually at $.99 (80 Microsoft points) a piece.

　　A complete list of tracks available for Rock Band can be found on Harmonix's official Web site.
