Adult Swim are back with their singles series. First out the blocks are Psych funk meddlers Unknown Mortal Orchestra. The track I’ll Come back 4 U is a surprisingly sweet sounding number that shows a more melodic side to the band. The Psyched out, almost harpsichordy, guitars that we fell in love with on their debut are still out in force. You can get a free download of the track over at the Adult Swim site.
