I offer as an example the saxophone playing of Eric Dolphy. Perhaps you are familiar with him. He was a post Bop progressive player that was very challenging to listen to. I'm not criticizing his talent or his music but he was very difficult to listen to. He was fond of making sounds with the saxophone which the saxophone wasn't designed to make. His riffs sometimes got lost completely from the structure of the tune he was playing.
On the other hand Miles Davis was also challenging to listen to. His playing was complex to say the least. But he didn't take a trip to Europe every time he fingered another valve. His work was always coherent and true to the structure of the music he was playing, even if it travelled beyond where most horn players went. Davis is an icon in jazz history and Dolphy is an interesting side note in comparison.
I guess I'm rambling. I think this is a good time to stop.
Well, this thread might grow into a multi-headed monster. Heh. At first I tried to resist in posting, but whatever. I really disagree with your views on Dolphy. He integrated himself very well, while maintaining his voice if you will, with some amazing ensembles. He died sooooo young, and yet his music was as influential to jazz as any. I am not familiar enough with Miles, though I've listened, studied, and owned his stuff a bit, but Dolphy is IMO on the Shorter/Monk/Mingus/Coltrane/Duke/Miles type of level of influence. To me, what you say is akin to something like "Mozart is an icon in classical history, and Haydn is a side note". Ok, Haydn
might not be on the same level to the eyes of the world population as a whole, but side note? FWIW, if I only had the choice of Mozart and Haydn, it would be tough, but I think I'd choose Haydn. And just as it would be tough for me to choose between Davis an Dolphy, I think I might choose the latter. I will say though having sat with transcriptions/scores of Davis solos in my jazz studies while listening, the harmonic and/or modal implications (temporally past or present) with a melodic instrument was extremely impressive to say the least. I once attended a sort of exclusive 30 person masterclass with Dave Holland at the Monk Institute, and I swear a large portion of it was his story of how his jazz career began in the most
insane manner, pretty much to blame/thank Davis for. Fun story.
If you think Dolphy is difficult to understand, you should try John Coltrane, particularly the stuff
after he sobered up. Or maybe you dislike Coltrane even more. His earlier stuff almost seemed to have even less cohesion, because the stuff in between the head/chorus was really being pushed. Latter stuff in a way seemed to be more integrated or pervasive/consistent in language/style, but a
lot more acerbic IMO.
