Nightlife Party Girls

1970s: Disco
By the late 1970s many major US cities had thriving disco club scenes which were centered around discothèques, nightclubs, and private loft parties where DJs would play disco hits through powerful PA systems for the dancers. The DJs played "... a smooth mix of long single records to keep people 'dancing all night long'" Some of the most prestigious clubs had elaborate lighting systems that throbbed to the beat of the music.
Some cities had disco dance instructors or dance schools which taught people how to do popular disco dances such as "touch dancing", the "hustle" and the "cha-cha-cha". There were also disco fashions that discothèque-goers wore for nights out at their local disco, such as sheer, flowing Halston dresses for women and shiny polyester Qiana shirts for men. Disco clubs and "...hedonistic loft parties" had a club culture which had many Italian-American, African American, gay and Hispanic people.
In addition to the dance and fashion aspects of the disco club scene, there was also a thriving drug subculture, particularly for recreational drugs that would enhance the experience of dancing to the loud music and the flashing lights, such as cocaine (nicknamed "blow"), amyl nitrite "poppers" , and the "...other quintessential 1970s club drug Quaalude, which suspended motor coordination and turned one's arms and legs to Jell-O". The "massive quantities of drugs ingested in discothèques by newly liberated gay men produced the next cultural phenomenon of the disco era: rampant promiscuity and public sex. While the dance floor was the central arena of seduction, actual sex usually took place in the nether regions of the disco: bathroom stalls, exit stairwells, and so on. In other cases the disco became a kind of "main course" in a hedonist's menu for a night out."
