The Game and Young Jeezy have both signed on to appear at the Boost Mobile Rockcorps concert at L.A.’s Kodak Theater on March 30. The concert will serve as a reward for 3000 young people who volunteered four hours of their time through the Rockcorps program which encourages community service in exchange for access to exclusive events. In 2006, Boost Mobile and Rockcorps hosted shows in Atlanta, Houston, Chicago and Detroit with volunteers contributing over 40,000 hours of service. For 2007, major events are planned for Atlanta's Fox Theatre and New York City's Radio City Music Hall. A recent survey of program participants showed that 80% of participants said they would be likely to volunteer again even without the promise of concert tickets or other rewards. Young people interested in contributing their time can call 1-888-ROCK-889, or go to for more information. Upon registration, they will be notified of volunteer opportunities in their area.
