Are you by chance referring to the time that "...a Chicago DJ named Steve Dahl detonated a dumpster filled with disco records between White Sox games at Comiskey Park, leading to a riot"?
At the time, I was a punk working in a great record store in the Western suburbs of Chicago (shout out to Johnny B Goode Records & Stuff!). I sent a number of promo disco records we'd received to Disco Demolition Night. I still laugh about how it turned out... Those were the days.
