Following Chicago’s Disco Demolition Night in 1979, disco music’s mainstream popularity fell into decline. In the early ’80s, fewer and fewer disco records were being released, but the genre remained popular in some Chicago nightclubs and on at least one radio station, WBMX-FM. In this era, Chicago radio jocks played various styles of dance music, including older disco records, newer Italo disco, electro, EBM tracks, B-boy hip hop music as well as electronic pop music. Some of these DJs also made and played their own edits of their favorite songs on reel-to-reel tape, focusing on the portions of songs that worked well on the dancefloor. Some even mixed in effects, drum machines, and other rhythmic electronic instrumentation in an effort to give songs more appeal. These edits and remixes were rarely released to the public, and even then were available only on privately pressed vinyl records or on mixtapes. These unique remixes became known as ‘Chicago house’ and The House Sound Of Chicago was one of the few commercially released albums to capture the city’s unique dance club sound.
