Been listening to this band for a sec, but opted to not write about them on the account of the reoccurring native theme around here. RIVAL TRIBES, a three piece from 'Bermuda' (says the MySpace) are, in laymen's terms, pretty awesome. These gents combine elements of psych, math rock, and punk to form a loud orchestrated mess of goodness. Their little 6 song demo (downloaded as EP) is most definitely worth the name-your-price price, but don't be stingy. And no, they are not like Animal Collective or MGMT - fuck those bands in the ass. MTV does not dictate who owns 'sound'. Listen to and enjoy their up and down 6 track treble-y journey.
PS Check out the youtube video, it actually looks like they put on a good show! Finally!
