Hailing from Austin and comprised of 21 people, Mother Falcon is an indie orchestra of sorts. Even at that whopping size, the exuberant tribe manages to make music that is cohesive and polished. With simple lyrics and moving (often tempestuous) arrangements, Mother Falcon is singularly adept at extracting precise emotions and at sweeping them all away. Recently, the group released the excellent and light-hearted pop single “Dirty Summer,” which hints at the possibility of more new material at Saturday’s show, as MF prepares to follow up their 2013 album You Knew. Locals Demitasse will open the night.
