Rock Band Network

CAMBRIDGE, MA and NEW YORK, NY – April 21, 2010 - Harmonix Music Systems and MTV Games, a part of Viacom’s MTV Networks (NYSE: VIA, VIA.B), along with T-Mobile USA, Inc., the official mobile partner of the Rock Band Network, today announced that Arizona trio Blackmarket have been selected as the Rock Band Network’s April “T-Mobile Artist-of-the-Month”.

"Blackmarket's unique mix of indie rock swagger and driving riffs made them the standout choice to be our first T-Mobile Artist-of-the-Month," said Paul DeGooyer, Senior Vice President of Electronic Games and Music, MTV Games. "Our partnership with T-Mobile enables us to highlight some of the truly great music in Rock Band Network every month for our millions of fans. Stay tuned . . . and in the meantime, check out Blackmarket's 'Tongue Twister Typo' ( http://t-mobile.rockband.com/artist-of-the-month)!"

As the April “T-Mobile Artist-of-the-Month,” Blackmarket will be featured for one month in promotions throughout the Rock Band Network music store and on the official game website including the new RBN content hub at http://t-mobile.rockband.com, which is fast becoming a rich source of information about Rock Band Network including Inside RBN, a source for consumers to discover new music, and Creators Club, a source for artist/authors/labels to find out more about the RBN authoring process.

Blackmarket have come a long way since their fiery debut in the hedonistic party town of Lake Havasu, Arizona. The band released their critically acclaimed debut album “The Elephant In The Room” in 2008. Performing live, the band has supported UK buzz band The Subways, stormed stages everywhere from Germany to Georgia, and stolen the show at the legendary Fuji Rock Festival in Japan.
