Incapable of not giving back to his city, Chance the Rapper has announced his latest good deed: an entire music festival of his own. The inaugural Magnificent Coloring Day will go down on Chicago’s South Side at U.S. Cellular Field (where the White Sox play) on September 24. In addition to Chance himself, Lil Wayne, Skrillex, John Legend, Alicia Keys, Young Thug, 2 Chainz, Tyler the Creator, and Lil Uzi Vert are all slated to perform. He’s also teased a “very special guest” as host. President Obama, maybe?! It’s Chance’s first-ever festival, but far from his first heroics: In May, just after his latest free album was released, he hosted a secret event for people in Chicago called the Magnificent Coloring World that ended up being a carnival and interactive arts fair in a warehouse. (He also recently called out Chicago amusement center WhirlyBall for being racist.) Tickets for his latest magnificent event go on general sale Friday.
