Interesting facts:
• Disco is a genre of dance music whose popularity peaked during the middle to late 1970s. It had its roots in clubs that catered to African American, gay, psychedelic and other communities in New York City and Philadelphia during the late 1960s and early 1970s. Disco was a reaction by New York City's gays as well as black and Latino heterosexuals against both the domination of rock music and the demonization of dance music by the counterculture during this period.
• According to music writer Piero Scaruffi the disco phenomenon spread quickly because the "collective ecstasy" of disco was cathartic and regenerative and lead to freedom of expression. Disco was the last mass popular music movement that was driven by the baby boom generation.
• Because the term "disco" became unfashionable at the start of the 1980s it was replaced by "dance music" and "dance pop" which described music powered by the basic disco beat.
