Chance the Rapper's been busy lately, but he found time to crash J. Cole's headlining set at Chicago's Spark in the Park 2014 to perform a song they apparently worked on together, "Thotty." You may remember the track as an untitled one Chance shared back in March, but now it's a bit more fleshed out - at least, according to some poor-quality fan-shot video. We're psyched to hear a recorded version, but this is an okay holdover - look at how much fun they're having! Check it out.
Check out video of the guys' debut performance.
