MANCHESTER, Tennessee -- A$AP Ferg was happy to share the spotlight Sunday afternoon at Bonnaroo.

While performing cuts from his 2013 debut album, Trap Lord -- including "Work," "Shabba," "Dump Dump," "Fergivicious" and "Murda Something" -- Ferg got the crowd involved, even letting some of his fans take the stage to perform themselves.

"Y'all look like a bunch of '300' soldiers out here!" Ferg shouted. "We're out here together, so if some sh-- goes down with A$AP, you got my back, right?"

He then gave the audience a few chances to prove it. "I think I need some ladies onstage here," the "Work" MC announced. Dozens obliged, some even crowd-surfing from way in the back.

At another point, Ferg parted the crowd temporarily so it could reconvene in a frenzied dance party. He then asked whether there were any MCs in the audience, and invited two guys onstage to spit a freestyle.

Harlem rapper Marty Baller also turned up for an assist, as Ferg did A$AP Mob's "Hella Hoes" and his boy A$AP Rocky's "Wild For the Night" collabo with Skrillex, who happened to curate an unforgettable Superjam on Saturday night.
