You've spent the last several months of your life in the basement, honing your Guitar Hero skills day and night, executing more acrobatically complex riffage than Robin Williams halfway through a week-long speed bender. The time has finally come for you to emerge pale and bleary-eyed from your Xbox-equipped subterranean womb, to show off your god-like skills--well, if you live in the greater New York area, that is.

Samsung and GH3 manufacturer Red Octane are co-sponsoring a "Guitar Hero Championship" tomorrow in NYC at the Samsung Experience, located in Columbus Circle's Time Warner Center. The tournament is scheduled from noon to 8 PM and requires a registration fee--$20 online or $30 at the door.

The grand prize includes a custom GH3 guitar and a Samsung P2 MP3 player. Runners up will receive a Samsung K3. For more information or to register, check out the event's official site.
