30th anniversary of the Disco Demolition Night: “Disco Demolition Night (sometimes known as Disco Sucks Night) was a promotional event that took place on Thursday, July 12, 1979, at Comiskey Park in Chicago, Illinois. It was held between games of a twi-night doubleheader between the Chicago White Sox and the Detroit Tigers. During the event, rowdy fans surged onto the field, and a near riot ensued. It would ultimately prove to be one of the most notable promotional ideas and one of the most infamous since “Ten Cent Beer Night” in Cleveland in 1974. The event is regarded as the culmination of a backlash against disco music that had an effect on the decline of the genre.” (Wikipedia). Check Steve Dahl’s tribute to the Demolition Night.
