I'm not sure why we seem to be accepting Miles as only an inventor on a small level - as I said earlier, he basically invented the group setup for hard bop, re-designed the entire approach to bebop in the direction of modality, set an entirely new aesthetic for jazz (cool), brought Coltrane into the fold in such a way as to allow him to develop his skills and become the most important post-modern improvising influence, hired Bill Evans, who than became the most influential pianist of the post-1960 era, created a group that basically set a template for post-bop group design (thinking Shorter/Williams/Carter/Hancock), basically invented fusion - what more can we expect from any one musician?
