Earlier this evening, Vic Mensa threw a meet and greet and surprise concert for his Chicago fans at storied boutique Leaders. Fans thought they were only going to be treated to a quick meet and greet — that was until Vic pulled up (in traffic) on Red Bull’s fire truck, Cate, and gave onlookers a full blown performance. Needless to say, it was lit.

Check out videos and pictures of this wild appearance and event below.
