Tune-Yards + Buke and Gass + Afuche

How cool is this bill? One-woman band Tune-Yards stars Merrill Garbus, whose every song seems born in some enchanted junkyard; her recent sophomore album, w h o k i l l, is one of the year's best indie-rock records, drawing cues from a range of genres and continents. Meanwhile, local art-pop duo Buke and Gass plays customized implements (a baritone ukulele and a hybrid guitar-bass) that may seem rarefied, but display a wide-eyed energy that could win anyone over.
