This is bonkers -- I don't really follow/listen to jazz, but was aware of "So What" and the other Miles Davis standards -- I had no idea he went this direction. Was he just stretching the genre as far as possible at this point? The "genre-stretching" thing is something I've been thinking about lately and trying to identify -- the band Swans has done this convincingly imo with rock, especially with the 2013 album "To Be Kind."
Hi :-) What genre? ..jazz?! I don't think of those second two as jazz. People play music, not genres. They and their music just have to be labelled to put in bins in record stores I guess. Some other Miles "directions":
Miles Davis - Kind of Blue (1959) [0] to Live-Evil (1971) [1] to Rated X (1974) [2]
