All electronic genres has its roots in House which was created by blacks Gen Xers in Chicago.
While Jamaicans and Caribbean folks of that generation were going to "bashments", blacks in Chicago were going to "house" parties. It's the music when I was younger, my young aunt's and uncles were in the basement with their friends partying to or going to clubs to hear or were playing at local college and fraternity parties.
Which is why it's interesting when I've been hearing multiple times in this thread that reggae was in it's heights in the 90's because it was pretty absent from our lives in Chicago in the 90's which was being dominated by House. Like I knew some tunes like Sister Nancy but not much more than that.
But to Suppers point about Afram musical insularity, House is still very popular locally but we don't have new artist furthering the progression of the genre because Hip Hop came in and crush the building and so now younger generations view the music as being "gay" or just not interested in any other music outside Hip Hop & R&B. That's what the legacy of Hip Hop, it promoted conformity and killed curiosity. Or it could be as one of the posters mentioned "the ultimate genre" taking in elements from all others, which would explain why many Aframs have largely abandoned the other genres of music we created. I don't exactly see Hip Hop that way though.
But as I was saying, I'm glad it picked up popularity by other black groups specifically in South Africa. I would rather the progression of the genre be spearheaded by other black folks than by whites, for instance, like Techno, which is the sister genre to House, was picked up and made popular by black Detroiters, but is completely white washed now.
