Up until now, the fast-rising Chicago rapper Vic Mensa has been known for a few things: Doing some songs with Chance The Rapper, showing up on the last XXL Freshmen cover, releasing last year’s promising Innanetape mixtape. This past weekend, he turned 21, and he marked the occasion by adding another bullet point to that list. During Damon Albarn’s set at New York’s Governors Ball festival, Mensa came out onstage to do his own version of Del The Funky Homosapien’s verse on the old Gorillaz track “Clint Eastwood.” Performing with a Britpop icon is maybe not the clearest or most logical route to rap stardom, but it’s definitely something. Watch video of the performance below.
