Let me pimp out: Powerglove
They do metal remixes of video game songs. And it's awesome. They may not be as operatic and original as The Protomen, or have the license-powered grandiosity of The Black Mages, but they're awesome. My personal favorites of theirs: Storm Eagle, Tetris, Blasting the Hornet, Omnishred (We're Gonna Need a Bigger Sword), Holy Orders (Be Just or Just Shred), Birth of a God, Red Wings Over Baron, and Dr. Wily's Theme.
