It’s one of the biggest weeks in music in New York City, and last night Joey Bada$$ got in on the action. During Pitchfork’s unofficial CMJ party at Villain, the Brooklyn up-and-comer stopped by to perform.

Luckily for those that missed the set, captured Joey doing “Hardknock” off his 1999 mixtape. Watch that up above and grab 1999 and the companion Rejex mixtape now.
