Mates of State played an early show yesterday at Mercury Lounge to show off some of their new tracks from Re-Arrange Us. The band's size has doubled for this album with two new members, who happen to be brothers, backing up Kori and Jason with a wide range of instruments: violin, cello, guitar, metallophone, shaker, and even a trumpet on one song. The new mates were not a part of every song nor were they really necessary on some of the ones they were, but their added instruments and sound helped to fill the stage and the room. Mates of States did not play a full set but they promised to be back soon for a proper headlining show.
