Though Vic Mensa and Skrillex just premiered their new collaborative track “No Chill” on Zane Lowe’s Beats 1 radio show, this is not the first time we’ve heard it. The duo debuted the song at L.A.’s Echoplex back in June and introduced it as a world premiere to “whoever got their camera on and shit.” Fun fact: When Mensa raps “Practice? What the fuck is practice?” on the hook, he’s riffing on that same famous Allen Iverson rant that Skylar Spence sampled on his own new single. Listen to “No Chill” below.

Mensa’s official debut album, Traffic, is due out later this year on Roc Nation.
