Chicago rapper Chance the Rapper and Skrillex have teamed up for a new song.

Debuted by Skrillex at a recent Brooklyn live show, it probably doesn’t sound how you expect it to – there’s no dubstep drop, for a start. In fact, it’s not far from the footwork that Chance jumps on at the end of his Acid Rap mixtape, and ends on a Joker-esque splash of synth squiggles.
