Rapper Chief Keef appeared via hologram at a Hammond music festival Saturday night, but police shut down his performance within minutes, according to the Chicago Tribune. The performance was part of a benefit to raise money for the families of Marvin Carr, a rapper from the south side of Chicago who performed under the name Capo, and Dillan Harris. Harris, who was 13-months-old, was stuck by a car that was trying to escape police during a chase following the shooting of Carr, according to the Washington Post.

Last weekend, a Chicago theater called off a similar show after representatives for Chicago Mayor Rahm Emanuel's office deemed Chief Keef "an unacceptable role model," whose music "promotes violence" and whose presence via hologram "posed a significant public safety risk," reported the New York Times. "I know nothing about Chief Keef," Hammond Mayor McDermott, 46, said. "All I'd heard was he has a lot of songs about gangs and shooting people - a history that's anti-cop, pro-gang and pro-drug use. He's been basically outlawed in Chicago, and we're not going to let you circumvent Mayor Emanuel by going next door."

The hologram of Chief Keef took the stage around 10:30 p.m. Hammond police shut down the show about a minute later, Mayor McDermott said. There were no arrests, citations or incidents as more than 2,000 fans were cleared from the park.
