What band is this PEASE HELP!!!

you love the band from a 50 second video clip?

I don't know what the fuck was going on. I could barely make the music out with the commentators/cheering.
 
Same, I actually did watch the video for whatever reason... and it was some godsmack sounding instruments and screamed vocals, all muffled out by the fans and commentators.
 
I'd say, forget about who that band is and look for some others on Youtube. That sound they have is pretty generic. You'll find something much better, and not through a UFC video.
