Earlier this month, Chance The Rapper announced that his production company, Social Function Productions, would be organizing a commemorative 50th anniversary concert for the Special Olympics in Chicago. The concert will be held in Northerly Island, Chicago on September, 21st, and all the proceeds will be going to the Special Olympics as well as Chance's charity, Social Works.

At the time, only the bottom half of the lineup was announced. While it already included some interesting artists on the roster, such as Motown legend Smokey Robinson, today Chance has announced the headlining acts of the show. One of them should be a surprise to absolutely no one, but the other should make for a pretty sweet show. 

As suspected, the main headliner for Chance's Special Olympics Anniversary show is Chance himself. While not a surprising addition to the roster, having the opportunity to see Chance live in concert, while also supporting a good cause is definitely a worthwhile experience.

The second headliner for the show is R&B megastar Usher. Sure, he might be going through some rough times at the moment, but no one's going to be thinking about that when Usher starts crooning out "Confessions Pt. 2." 

Also added to the lineup is Chance's frequent musical collaborator, Francis and the Lights, as well as Pittsburgh singer, Daya. Francis recently started rumors that Chance and Kanye West might be coming through with a collaborative album in the future.
