Avant-garde outfit Pretty Bird is unlike any other band in Athens, or just about everywhere else. Featuring a rotating cast of characters but anchored by the tight-knit trio of Jacob Deel, Valerie Lynch and David Chandler, the group plays a severely outré a cappella-based form of what it terms "hip-hop," but which is often nearly unrecognizable as such. Ever amorphous, the recent inclusion of deep-house rhythms and live band instrumentation seems to hint at a slightly more accessible new direction. (Read an interview with Pretty Bird on Homedrone.) Saturday's bill centers on former PB-er K. Jared Collins and his k i d s project, which will record a live, David Barbe-helmed EP at the show with the help of Pretty Bird and various other members of local anti-pop kvlt the Birdhouse Collection.
