Husband-and-wife duo David Wax and Suz Slezak, known as David Wax Museum, returned to the Barn for the second time to share their rousing Latin-folk-inspired indie rock. They performed a stripped down set of songs from their latest EP A La Rumba Rumba, a celebration of the Latin folk music that inspires them most, as well as tunes from their fourth full length album, Guesthouse.
