Although Chief Keef's recent attempt to perform near his hometown of Chicago (in Hammond, Ind.) was thwarted by local police, the rapper is not willing to give up.

Keef and Greek billionaire backer Alki David announced the All-Star Stop the Killing Now Hologram Benefit Concert will be held simultaneously in Chicago, New York and Los Angeles this September, to be live streamed on FilmOn.com. David is the creator and driving force behind FilmOn.com. The concert will raise money for families affected by violence as well as charities working to stop the violence in Chicago's South Side.

Despite resistant from Chicago Mayor Rahm Emanuel -- who seems resistant to the idea that the gang-affiliated rapper has changed his ways -- Keef and David intend to bring the former's hologram to Chicago.

The all-star lineup has yet to be revealed.
