Swear and Shake + These Animals + Tall Tall Trees

Swear and Shake, a local quartet built around the harmonies of dual frontfolk Kari Spieler and Adam McHeffey, offers postcard-perfect indie-folk with an undercurrent of sly humor. Also on the bill is Tall Tall Trees, which plays low-key, rootsy throwbacks that would have found a nice place in O Brother, Where Art Thou?
