Unknown Mortal Orchestra have just embarked on a month-long tour opening for Grizzly Bear, but before their touring schedule took over, the Portland outfit has been hitting the studio. The band is reportedly working on the follow-up to their fantastic self-titled debut, which dropped in June of last year, and the results are good. First, we heard the Adult Swim Singles Program release "I'll Come Back 4 U", and now the group have dropped a new track titled "Swim and Sleep (Like a Shark)". The odd-yet-groovy psychedelic jam will be released as a tour-only 7" through the band's new label Jagjaguwar, so make sure to pick it up while you have the chance. If not, you can always stream it below.
