Kendrick Lamar brought the DAMN. tour to Chicago on Thursday night, and the rapper surprised the crowd by bringing out the city's own Chance the Rapper. The two artists performed a spirited version of Chance's "No Problem," which the audience gleefully sang along with.
"So much love that I gotta make sure I give it back. Let's do something special," Kendrick told the audience before Chance emerged from below the stage.
