That sounds nice but jazz has historically been VERY trend-conscious, well after it ceased to be pop. And I'm not even referring to Miles Davis, no, even in fucking *free-jazz*, you can clearly notice that the music changed from a more post-Coleman approach to a post-Coltrane approach as the 60's progressed with "everyone" just happening to become "spiritual" and droney-sounding and interested in eastern mysticism and the music as a healing force. Is it just a coincidence that all those artistic people happened to go in that direction at the same time? Or that the Blue Note guys had a tendency to put one groovy, dance-jazz tune on records after the Sidewinder hit (seriously, listen to Herbie's admittedly stellar "Empyren isles" and tell me that "Cantaloupe island" doesn't sound out of place amongst all the advanced post-bop)? Or "everyone" jumping on the fusion-trend including people who had previously expressed scorn at amplified music?
I love jazz as much as possible but that whole "they are pure artists playing themselves"? I never bought it really...
