Dragonforce
 

If you haven't heard these guys, you haven't lived. One of the greatest metal bands. The lead guitarist (Herman Li) is one of the most talented I've ever heard. And he's fast. Not like, usless pinky tapping fast, but melodic awesomeness fast. I'd check out Valley of the Dammed and Sonic Firestorm. Their newest album Inhuman Rampage is kind of a step in another direction, but it will grow on you. But warning, lyrically, they are quite cheesy.
