On this day in music history: July 12, 1979 – WLUP radio DJ’s Steve Dahl and Gerry Meier stage a “Disco Demolition” rally at Comiskey Park in Chicago. The event takes place during a White Sox/Detroit Tigers doubleheader blowing up a bin with thousands of disco records, and it quickly spirals out of control. 50,000 plus fans attend the event which degenerates into a full scale riot, with people storming the field, setting bonfires to the debris littering the field and vandalizing the ball park. Chicago Cubs public announcer Harry Caray attempts to bring calm to the crowd by singing “Take Me Out To The Ball Game”, but it does not quell the mayhem as the mob goes unabated. Thirty nine people are arrested, and the second ball game are forfeited. The event goes down in infamy, and signals beginning of the end of the Disco Era in popular music.
