Earlier this year, Puff Daddy led much of his '90s Bad Boy Records roster through a triumphant reunion show in Brooklyn. And now he's taking that roster on the road, doing big nationwide '90s-nostalgia shows with Mase, Lil Kim, the Lox, Faith Evans, Carl Thomas, Black Rob, Total, and French Montana. The tour had to be delayed when Puffy was injured, but it finally kicked off last night in Chicago, and Puff had a few famous surprise guests with him. Chance The Rapper, who is basically the mayor of Chicago now, showed up to do "No Problem" and to cause general pandemonium. He also brought out another Chicagoan, the R&B great Jeremih, and his sang his big single "Oui" with Chance still onstage. And Puffy also introduced another '90s titan, the not-imprisoned-right-now DMX, who also led the Bad Boy roster through a prayer circle backstage. Watch some fan-made videos from the show below.
