Pattern is Movement is an American indie rock band from Philadelphia, Pennsylvania, and established in 2001. They have been categorized by some reviewers as a math rock group, and compared to groups such as Don Caballero, Sunny Day Real Estate, and Pinback. However, as the band moved from a five piece to a two piece, their sound moved away from the angular sound of previous records and now to a more melodic heavy composition structure with sing-a-long choruses. The current two piece sound can be attributed to influences such as Dirty Projectors, Beirut and Grizzly Bear.
