During the Viceland showcase at SXSW, Action Bronson decided to invite several rising rap stars out on stage to spit some acapella bars. Most notably, Bam Bam invited Chicago's Chance The Rapper to step up to the mic. Rather than spit a freestyle off the dome, Chance ran through one of his verses off of his track "Brain Cells" which appeared on his debut mixtape 10 Day.
