Jazz, to me, a layman to the genre comes off as anything from Miles Davis and Duke Ellington to soundtracks composed for animes, to progressive epics that span twenty minutes and spin into a free form improv that’s somewhere between art and math.
But aside from it being a flavor other things come in, like a jazzy rock band, Mars Volta or a jazzy metal band, like Opeth, or a jazzy singer, like Michael Buble, I don’t know jazz.
I don’t think as a normal person that I’m exposed to pure “jazz”, whatever it dilutes into, but I’m fascinated by the chance that there might be something I’m missing that you might mention.
As much as any treaties and agreements made anywhere else, if I had to guess.
Hardly any. I feel two might be optimistic.
