It's possible that I've mentioned these guys before, but they deserve a thread. I'm not joking when i'm saying that they're what the Mars Volta would sound like were they ten years younger. Powerful, extremely talented, and they even have a Spanish singer like Cedric! also, you can download their entire first EP for free here i listen to this at least once a week, and it still wows me. They even have the percussion section down like the Mars Volta.
