E for All Expo Sets the Stage for Rock Band Mobile Tour ; Fans Face-Off for the Opportunity to Rock on MTV at This Week’s Inaugural Video Game Event

FRAMINGHAM, MA – OCTOBER 16, 2007 – IDG World Expo today announced that the widely successful Rock Band™ mobile tour will be making its next stop at the upcoming Entertainment for All™ Expo (E for All™) ( www.EforAllExpo.com ), scheduled for October 18-21, 2007, at the Los Angeles Convention Center. The coast-to-coast tour, sponsored by music-based games developer Harmonix, MTV Games and distribution partner Electronic Arts (EA), gives consumers the opportunity to experience the highly anticipated Rock Band video game before its debut in November.

During all four exhibition days, E for All attendees will have the opportunity to become ultimate rock fans and budding musicians as they participate in a “Rock Off” audition for an opportunity to appear on MTV’s TRL. The Rock Band tour bus main-stage will provide aspiring rock stars with the chance to jam like the best of them – putting their guitar and gaming abilities to the test.

“We are thrilled to have the Rock Band mobile tour on board for E for All,” said Mary Dolaher, CEO of IDG World Expo. “E for All is all about the games and giving fans a chance to test drive highly anticipated titles, and Rock Band is sure to be a hit with our attendees. And the concert element brings an exciting interactive experience to the E for All show floor.”

In addition to their on-site plans, aspiring rockers will have the chance to participate in a nationwide casting call through MTV’s Rock Band “Rock Off” events. Performers brave enough to play on the Rock Band tour bus main-stage will be captured on video and viewed by MTV casting directors. Two bands will be chosen and flown to New York City to spend a day with a real rock band and receive true rock star training. The auditions will culminate with the bands rocking on-air on MTV’s TRL Rock Off event during Gaming Week. One band ultimately will be chosen to open on a real stage for a yet-to-be-named band.

Rock Band outfitted tour rigs recently began touring the country – embarking on a 24 city tour – from California to Cleveland, Atlanta to Arizona and everywhere in between – giving music fans the chance to master the lead/bass guitar, drums, and vocals as solo artists or cooperatively as part of their own band. Specific locations for each city will be released separately. In addition, fans can visit http://www.rockband.com/tour for more information on dates, locations and Rock Band news.

EA will serve as the exclusive distribution and marketing partner for Rock Band, managing distribution for the game in the U.S., Europe and Australia. For more information on Rock Band and Harmonix Music Systems, please visit www.rockband.com and www.harmonixmusic.com .
