They're a non abrasive math rock band from Chicago pushing the lines of post-rock as many math rock bands do. I'd say As Seen From Above is their best release though they have a pretty solid discography. They have pretty nice progressions and a fitting tone. They're along the line of Don Cabellero, Pele and Piglet. I can up something if anyone's interested.
