Chicago's number #1 urban station 107.5 WGCI kicked off their Summer Jam concert series, this past weekend, with some of the biggest names in music. The event took place at the City's United Center and the place was packed with loud screaming fans, showing love for their favorite artists.

Kicking off the show, Chicago's own "Bop Kings" Dlow and Stunt Taylor hit the stage to perform their latest singles to get the crowd hyped, followed by performances from K Camp and Ty Dolla $ign.

Next in the show, the "King of Memphis" Yo Gotti hit the stage to give the audience a hard rocking performance with his taste of the streets, while Jennifer Hudson followed and smooth things out with her latest single produced by Timbaland called "Walk It Out."

Later, the "King of R&B" R Kelly took center stage and lets just say the rest was history. Kellz made sure he gave his hometown exactly what they wanted, singing nothing but hits. He took the crowd on a journey with classic from his 12 Play album all the way up to his latest album, Black Panties.

Ending the night off, Roc Nation's very own J Cole hit the stage with his live band followed by Trey Songz, who had the ladies standing on their feet screaming and calling out his name.
