If you read Kotaku or watch videos on YouTube, you’ve probably seen this already. For the uninitiated, it’s a (badly shot, and with dodgy sound) video of a high school band rocking out the Halo 2 theme on stage.
Kotaku have covered it comprehensively with an original post and a follow-up interview with Hanah Stuart, the talented violinist (she’s now at Juilliard!).
More impressive, Marty O’Donnell, the audio director of Bungie complimented the show on the Bungie-hosted Halo forums (fora?).
