And there is also a good amount of jazz music with lyrics. In fact, there is very little music out there in any genre that has the lyrical heft that Jon Hendricks or Kurt Elling have in their denser vocaleses. But yeah, on your first point there, I remember a big double-bill concert around here about ten years ago. The first half was fairly traditional jazz, well-attended and apparently well-liked. The second performer's music could best be described as a quick, semi-recognizable head followed by minutes of endless sixteenth notes without any appreciable (to me, anyway) form or structure. There was obviously an incredible amount of skill on display, but I found it unimaginably boring. I wasn't alone: after about ten minutes of the second half, there was a steady stream of people getting up and leaving during the performance. So did I eventually.
