Fresh off the release of his Floor Seats album, ASAP Ferg appeared on Sway in the Morning to discuss the project, his personal style, and ASAP Rocky's recent legal battle. But the highlight of the interview occurred at around the 29-minute mark, when Chance the Rapper decided to pop in unexpectedly.

"We got the richest n***as in Chicago in here right now," Ferg said, as Chance and his crew greeted everyone in the studio. Ferg then suggested he and Chance drop a back-and-forth freestyle.

"I'm so ready for that," Chano responded. "Let's do it."

The rappers agreed to do "a little narrative" as DJ Wonder dropped the beat from OutKast's "Elevators." Ferg set the comedic tone, rapping about a fictitious woman with whom they had both hooked up. As the freestyle continued, Chance began taking a stroll down memory lane, reminiscing about the times he used to stay with Ferg when he visited New York.

"That was before you was listening to gospel music," Ferg rapped. "And that was when you used to be rockin' to it, on the tour bus."

Chance interjected: "I'm married now/Don't get carried now, don't get carried away," he rapped with a laugh. "I got the ring, shout out to my bae."

The rappers then went for round two, delivering freestyles over JAY-Z's "Where I'm From." Chance's brother, Taylor Bennett, also got in on the action.

As part of his promotional run, Ferg also stopped by the Beats 1 studio to speak with Everyday Struggle co-host Nadeska Alexis. You can watch the sit-down below.
