Chance the Rapper is playing a surprise show at Metro tonight

He might not be listed on the lineup, but Chance the Rapper's surprise appearances at Lollapalooza have been among the biggest highlights of the four-day fest. On Thursday night, he showed up during a headlining set from Flosstradamus to perform a couple tracks, and on Friday he turned up on stage with Future for a rendition of his single, "No Problems." 

Now Chance is celebrating the end of Lollapalooza with a show of his very own tonight at Metro. Doors for the 18+ gig open at 10pm and tickets are $40, but you can't just buy a pair online. Instead, tickets are only being sold at the Metro's physical box office—and they're on sale now. 

Just like tickets to Chance's Magnificent Coloring Day music festival at U.S. Cellular Field in September, this "secret" show is guaranteed to sell out extra quickly. Plus, you're almost guaranteed to see some special guests appear with Chance—he's got a ton of famous friends in town for Lollapalooza this weekend.
