On December 3, 1979, the Riverfront Coliseum in Cincinnati, Ohio, was the site of one of the worst rock concert tragedies in United States history. Eleven fans were killed and several dozen others injured in the rush for seating at the opening of a sold-out concert by The Who. The concert was using festival seating. When the crowds waiting outside heard the band performing a soundcheck, they thought the concert was beginning and rammed the still-closed doors, trampling those at the front of the crowd.
