Also catch the pairs collaboration on 'Favourite Song.'
Fans at the Chicago stop of Childish Gambino's 'Deep Webb Tour' got an extra special performance this week when the '3005' rapper was joined on stage by rising rap star Chance The Rapper.
The two went old-school, taking ten minutes out of the show to let loose, performing impressive freestyles. Watch the two rappers spit everything from The Illuminati to women in the video above - the picture, which was captured by someone in the crowd - is a little distorted, but this is all about the audio.
