But disco did not start in New York and you certainly did not have to live there to know what it was. Particularly considering it's roots. Here's an excerpt from an interesting article I think you might enjoy:
--Disco, such a common word today, but its origins actually started in the Big Band era with the radio DJ's (disc-jockey). The Disc-Jockey would be the one who made the announcements and played the 33 1/2 LP and 45 rpm records (a flat 6" or 12" Disc with recorded music). The DJ's would eventually have their own TV, Radio and Movie shows such as DJ's - 'Dick Clark and Allan Freed'.
-- This was to eventually get the "DJ's" into the nightclubs and start the disco trend (using records/discs rather than live bands). It was much cheaper for the club owners than hiring the bands and the music was much more varied and up-to-date. The first Disco club was the Peppermint Lounge in Paris, France which opened in the 1950's. This would open the door to other establishments over time. The first Disco in the USA was the "Whiskey-A-Go-Go" on Sunset Blvd. in Hollywood (now named The Whiskey).
-- By the 1960's a new dance fad had started named the "Twist" and the Peppermint Lounge in NYC was to become famous, this started many night clubs dropping the bands and hiring a Disc-Jockey. Playboy had started a sexual revolution which was not yet realized and the 'Pill' was gaining momentum. Many of these clubs would follow the whiskey and Peppermint Lounge with some adding a touch of burlesque such as the topless Batman-A-Go-Go in Los Angeles whose dancers would dance in golden cages. Others would have male and/or female erotic dancers dancing on pedestal stages, in cages etc., sometimes scantly clothed, sometimes not. One of the original and popular Los Angeles DJ's of the time was Kenny Wetzel who talked the owner of the Staircase nightclub in Downey, California to hire him as a DJ, He became a major success till he retired in 1998.
-- In the Late 1960's, the disco dance craze was not really apparent yet. Some Cuban dancers in Florida where dancing a form of salsa and swing to the experimental disco sounds in the late 1960's. About 1968 a new type of electronic music (synthesizers) was making an impact and a new music was being born. The Cubans and the new music formed to create disco music ... a kind of hard hitting, thumping continuous beat that could be mixed from one song to another without stopping the music. By 1970, these couples would start doing what was finally tagged as 'Disco Swing', the public would later become confused and call it the Hustle (Van McCoy), which was actually a line dance, however the name stuck for the better. The discos were now getting high tech and the money was being invested in fancier nightclubs. The sexually free public was now comfortable with being a Playboy/girl as well the 'Pill' being a normal thing and was ready to let loose.
