Slightly mathy instrumental rock that is very nice to listen to. The bass player uses an upright, which gives a different feel than similar bands. A similar band might be Unwed Sailor or even Toe.
And as a disclaimer, please buy things from these musicians if you like them, or try to catch them on tour, or at least tell your friends about them. I've thought about taking this down, but I think there are both pro's and con's, so just try and support good music, and I will too.
