Post-disco is a genre of electronically progressive rhythm and blues music formulated in the late 1970s but is more commonly used as a term to describe an aftermath in popular music history c. 1979–1986, imprecisely beginning with an unprecedented backlash against
disco music in the United States, leading to civil unrest and a riot in
Chicago known as the
Disco Demolition Night on July 12, 1979, and indistinctly ending with the mainstream appearance of
house music in the late 1980s. Disco during its dying stage displayed an increasingly electronic character that soon served as a stepping stone to
new wave,
hip-hop,
euro disco, and was succeeded by an underground club music called
hi-NRG, which was its direct continuation.
