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. The playing field was so damaged by the explosion and by the fans that the White Sox were required to
forfeit the second game to the Tigers.
In the late 1970s, dance-oriented disco was the most popular music genre in the United States, particularly after being featured in hit films such as
Saturday Night Fever (1977). However, disco sparked a major backlash from
rock music fans—an opposition prominent enough that the White Sox, seeking to fill seats at Comiskey Park during a lackluster season, engaged Chicago
shock jock and anti-disco campaigner
Steve Dahl for the promotion at the July 12 doubleheader. Dahl's sponsoring radio station was 97.9
WLUP, so admission was discounted to 98
cents for attendees who turned in a disco record; between games, Dahl was to destroy the collected
vinyl in an explosion.
White Sox officials had hoped for a crowd of 20,000, about 5,000 more than usual. Instead, at least 50,000—including tens of thousands of Dahl's adherents—packed the stadium, and thousands more continued to sneak in after gates were closed. Many of the records were not collected by staff and were thrown like
flying discs from the stands. After Dahl blew up the collected records, thousands of fans
stormed the field and remained there until dispersed by riot police.
The second game was initially postponed but was forfeited by the White Sox the next day by order of
American League president
Lee MacPhail. Disco Demolition Night preceded, and may have helped precipitate, the decline of disco in late 1979; some scholars and disco artists have debated whether the event was expressive of
racism and
homophobia. Disco Demolition Night remains well known as one of the most extreme promotions in MLB history.
