After releasing a solid debut LP last year, Portland-based weirdo-pop wizards Unknown Mortal Orchestra are hard at work on their second full-length for new label home Jagjaguwar. Before that, they'll release a tour-only 7" for the label, which will be sold on the band's outing with Grizzly Bear. "Swim and Sleep (Like a Shark)" is the A-side, and it'll be backed by another new one, "Waves of Confidence".
