Joey Purp has been not-so-quietly coming up in the Chicago rap scene for a while now. His contemporaries like Vic Mensa, Kami, and Towkio have a lot of respect for him as an artist, which is why they agreed to perform with him during his set on the blue stage on Sunday. The fun never ended for Purp, who had guys with super soakers and water balloons cooling down the crowd, and a some confetti cannons for the finale.
