Chance The Rapper already got us hyped when he performed alongside Kendrick Lamar during Earth, Wind & Fire’s show last night. In another headline-making appearance, the Chicago rapper was around for SuperJam and he made sure to give fans something memorable. During Pretty Lights’ DJ set of dance songs, Chance surprised everyone when he hit the stage to cover throwback cuts like “Juicy” and “Summertime.” The set also featured a duet by Jon Hamm and Zach Galifianakis, as well as more artists like SZA, Bleachers' Jack Antonoff, and DMC of Run-DMC to perform a mix of original and covers.
