House music originated in the gay mostly black clubs in chicago in the 80's. the roots of house are disco and soul.
Kinda like how hip hop was a mostly black artform that got embraced by some whites and latinos, same thing with house.
so it is an AA artform
but outside of chicago, detroit, b-more and jersey and perhaps NY most blacks are not fukking with house music like that unless theyre 'different'.
they dont even mess with juke or ghetto house outside of the cities i mentioned.
try playing the perculator in memphis or Alabama and see how they react
