Apparently once just wasn't enough.
The festival, open only to Chicago residents 13-24-years-old, went down at Northerly Island today. Chance joined headliner Donnie Trumpet onstage, and the duo performed parts of their recent collaborative album, Surf. In an even bigger surprise, Kendrick appeared out of nowhere to deliver "m.A.A.d city" and "i," and fans went absolutely bonkers. Those lucky, lucky kids.
Check out some footage and pics of Kendrick, Chance, and Donnie joining forces.
Chance just brought out Kendrick. What a beautiful moment. pic.twitter.com/7e1RFDXl0i— Lyrical Lemonade (@LyricaLemonade) June 25, 2015
