do you know how broad jazz is?
Too many different types of jazz
Big Band
Soul
Soul-Jazz
Blues
Swing
Which branched to:
RnB (Rhythm and Blues)
Funk
Hip Hop
and what not?
But in which case, if you're talking THAT kind of jazz, with the big bands, the only common element I see, especially after WW2 where it was popular, was that the majority of jazz contenders were black? Not gay?
