Jessica Risker lets the sunshine into her delicately folky, faintly psychedelic songs, but that sunshine casts a shadow. The Chicago-based songwriter bubbles and charms amid droning kraut propulsion while the cover of her second album depicts the artist in an upper floor of a weathered city building, holding helium balloons, and that about sums it up. Risker floats weightless fantasies from urban grit and realism.
