This is just my opinion, mind you, but Disco, in the incarnation we know it, with hindsight, was created by David Bowie. After his This White Duke Era, he made Young Americans, an album that mixed the soul (black music) and the pop (white, obviously) that where dominant then. In many ways, you can say that he did for soul (for good or bad), what Elvis did for blues some 20 years earlier, and what Eminem is doing right now - i.e. making black music more accesible to white suburban kids. Also, in a way, less ‘dangerous’ from the parents point of view.
I know the whole issue is potentially loaded with biases concerning race and especially sexual preferences. I was around 15 when disco became big and never had an idea, at the point, that the fashion and stuff that we all thouight was so cool and bought, was really gay fashion, from the US.
The discoteque, a place where they spin records and people dance, was maybe invented at the Whiskey a go-go. The idea we have now, that something must be a certain style, so anyone can dance to it, didn’t figure in the equation back then. Heck, discoteques pre-disco, played Deep Purple or Janis Joplin.
The thing is, the music was never important. It was a place for mating rituals under the influence, for young people. As long as the music was lod and you could grope a girl in the dark, nobody gave a shit about what was played.
At about the same time, black musicians were getting bigger and bigger acts. Earth Wind and Fire, Funkadelic, Parliament… even today, George Clinton brings 15 people on stage. No clubs could afford such big acts so they movied to the auditoriums and bigger theatres (Think Apollo in NY), and finally gave way to what was to become hip-hop around 1980.
Problem with disco, was that everybody wanted in, to make money. And productions were fairly cheap to do, so the market was flooded with really, really awful music. And I use music in a very loose way here. So disco killed itself, just when it should have taken over.
It’s still out there. Modified and alive in just about every dance music you here. And it’s been a full circle, since so many black artists have been sampling songs from white atrists who ripped off the black music to begin with.
I could make this more coherent, but I guess I’ve rambled enough as it is. Bottom line, in re ýour OP, just about any music was played in discos, before Disco.
(I’ve worked as a DJ and in radio since 1976, so I’ve been around for most of this time. And remember fairly well what went on before 1975. That I was, and am, based in Sweden, doesn’t matter. I’ve got enough Americans friends to know that things might’ve happened a few months apart, but it was basically the same.)
