Rock Band and Guitar Hero: World Tour can join the teen-focused Power Chord Academy for their "GameROCKERS" program.
The three-day program allows musically-inclined gamers a chance to show off their original digital compositions, join competitions and win prizes. Also, if three days sounds too long, then there's always Power Chord's "iROCKER." It's basically a one-day version of the other program. Power Chord's website has details on dates and locations for those planning to make the trip out there.
