Starting Sunday in Las Vegas, a "Rock Band outfitted tour rig" will begin a 24-city tour, allowing wannabe rockers to rock out on a full-on concert stage, light show included. In addition, participants will have the option to try out in a "Rock Off" for the opportunity to appear on MTV's TRL, which just hasn't been the same since Carson Daly (pictured above) left.

"We simply couldnÂ’t wait any longer to get the game into consumers' hands and give them a taste of the power of the Rock Band experience," said MTV VP Jeff Yapp. The two selected Rock Off winners will play on TRL and get to hang out with a "real rock band" in New York.

Out of the two bands, a winning group will be chosen based on its mastery of badical plastic shredding and given the opening slot before a "yet-to-be-named mega band" at Rock Band's launch concert. More information will be posted on the tour at the Rock Band Web site starting Sunday, but check out the known dates below.
