For those of you that have played Borderlands, you've heard this band before and haven't even realized it. Their song "Ain't No Rest For The Wicked" was used in the opening of the game, which in my opinion was the best song they could have ever picked for the opening introduction to the game, because it fit the theme perfectly.
(the intro is actually skipping the 2nd chorus and 3rd verse, jumping into the final chorus)
Anyways, the band isn't a one hit wonder. This is the opening song to their self titled debut album.
The entire album is pretty good from start to finish, it's something I'd highly recommend for expanding your music collection. Oh, and from what I've read the lead singer has tourettes is apparently hyperactive and refuses to take medication for it.
