Atlanta’s Midtown Music Festival, an event that draws tens of thousands of fans annually to the city’s Piedmont Park, has been canceled. The reason is because Georgia’s gun laws would not allow organizers to ban firearms, according to a person familiar with the decision, who asked not to be identified.

The event, scheduled for September 17-18, was set to feature headliners My Chemical Romance, Future, Jack White and Fallout Boy. Live Nation Entertainment Inc., the organizer of the event, said in a Facebook post that the concert was canceled “due to circumstances beyond our control,” without elaborating. Peter Conlon, Live Nation’s Georgia and Alabama bureau chief, did not respond to requests for comment.
