Though they just hit the road with Grizzly Bear, retro pop Kiwis Unknown Mortal Orchestra have reportedly been hard at work on the follow-up to their excellent self-titled debut. They shared one of their new compositions, “I’ll Come Back 4 U”, via the Adult Swim Singles Series earlier this summer. Another one, entitled “Swim and Sleep (Like a Shark)”, will be included on a tour-only 7″ being put out by their new label Jagjaguwar. You can also stream the pysch-pop number below (via Pitchfork).
