Disco Demolition Night was a Major League Baseball (MLB) promotion on Thursday, July 12, 1979, at Comiskey Park in Chicago, Illinois, that ended in a riot. At the climax of the event, a crate filled with disco records was blown up on the field between games of the twi-night doubleheader between the Chicago White Sox and the Detroit Tigers. Many of those in attendance had come to see the explosion rather than the games and rushed onto the field after the detonation.
