Lollapalooza kicked off in Chicago yesterday, and the first day of the festival brought some surprise guests to Grant Park. Chance The Rapper made an appearance during Flosstradamus’ set to perform the Coloring Book tracks “No Problems” and “Summer Friends.” Chicago Bulls player Dwyane Wade also showed up during that same performance, along with Michelle Williams and Post Malone. Here’s some photos and videos of those appearances via TimeOut:

First Daughter Malia Obama was also spotted wandering the Lolla grounds, having wisely skipped out on the boring (but historic) Democratic National Convention festivities in Philadelphia to rock out to some Cashmere Cat.
