It was around when I was in junior high though I guess on it's last legs (77-79), soon to be replaced by "new wave". I heard plenty of it on the radio, school dances etc, but was never moved enough to seek it out and own it, though my brother did give me Rod Stewart "Blondes Have More Fun" picture disc for my new turntable which was his "disco" album, as many other established acts did "disco' albums later to be followed by "new wave" albums (Alice Cooper "Flush The Fashion" anyone?) I was oblivious to it's origins from the gay club scene in NYC because by this time is was so homogenized and mainstream. But what I remember most from that period was being introduced to early Rap & 70's funk, the later which I guess was also part of the genisis of Disco. The school I went to was not diverse at all. Maybe 15 black kids total. My friend Robert Love was from Texas and from a world completely unlike mine. Never heard him play any disco, but he loved to dance and had the moves back then. Instead of Disco, he turned me onto Parliment, Bootsy Collins and also Curtis Blow (mostly by sneaking into his older brother's record collection when he wasn't home) and by turning me onto local radio station KDAY. But as far as Disco, it still really hasn't grown on me, not even as something campy, although I do laugh at that scene from the sitcom Malcom in the Middle when the dad is doing rollerdisco to that song "Rollercoaster" or was it "Funkytown". But I had no qualms cranking up D.O.A.'s song "Disco Sucks" (later to be reborn as New Wave Sucks) when I was turned on to it in 1980. Even that late in the game, TV disco dance shows like "Solid Gold" were still on the air.
Sorry, this was a pretty long winded answer just to say, naw, not my thing, there's too much good music I haven't heard yet and too little time to spend it listening to Disco.
