Today Unknown Mortal Orchestra released a new song, "I'll Come Back 4 U," through the Adult Swim Singles Program. It's a sunny psychedelic track, suited for playing on repeat while you're posted up in a park, just lounging. Since the song is hosted by Adult Swim, we can't help but picture/hope for a video featuring old favorites Aqua Teen Hunger Force, with Meatwad twirling around to the beat. The band's drummer is a new edition: Julien Erhlich left the group and joined Smith Westerns. Gregory Rogove, who also plays drums for Devendra Banhart, is manning the kit for now.
