Flosstradamus hinted there would be surprises at their 2016 Lollapalooza set Thursday night (July 28) and they delivered big time with guest spots by Chance The RapperMichelle Williams leading the crowd in a Destiny’s Child sing-along, Post Malone, and NBA star Dwayne Wade.

J. Cole was leading the charge on the south end of Grant Park while Lana Del Rey held court on the north end, but the Flosstradmus party bloomed in-between on Perry’s stage to a packed crowd that even included one elderly woman shaking her ass in the front row along side multiple younger generations.

The overall feeling of huge Chicago pride was no coincidence — Chance wasn’t the only Chi-town talent on the stage. Williams hails from nearby Rockford, Ill, Flosstradamus themselves are Chicagoans, and Wade recently announced he’s joined the Chicago Bulls.

No one could resist joining in on Destiny’s Child megahit “Survivor” with Williams, but arguably the hugest roar from the crowd came for Chance, who was ready with “Summer Friends.” Welcome home.

Fuse talked to Flosstradamus recently at Bonnaroo. Check out that video below.
