Going insane looking for a song, please help

This is a bit (bit? Hah) of a long shot, but here goes. I heard a song about three years ago in a place called Pandora's Cup in Minneapolis, Minnesota, and immediately loved the song. Unfortunately, it was long over and we had moved on before I could ask any of the employees about it.

The only things I really remember about the song were that it was pretty upbeat, with a strong bassline (reminded me of U2's rendition of the Mission: Impossible theme a while back, only faster with a bit less tone variation), with quick percussion keeping pace and a nasaly-sounding vocalist.

If anyone could point me in the right direction, I would be eternally grateful. This has been driving me nuts for three years now.
