I don't know a whole lot about The Summer Pledge, aside from the fact that they've stuck it out in their hometown of Detroit, valiantly resisting the Williamsburg exodus, but other than that they're an obscurity to me. "B's Teeth" kind of fell into my lap not long after listening to the new Mars Volta, and though it's no math rock it does occupy a clever ground midway between prog and, say, Vampire Weekend. If you're interested in hearing more there's a link to a free download of their first album, You Are You, over at the band's website. Their sophomore LP Vessels will be (self?) released May 10.
