Last, Chick Corea, Keith Jarett, Herbie Hancock, are NOT fantastic classical musicians, for god's sake. They aren't even comparable to even the standard young conservatory student.
For someone who's apparently figured out the entire jazz world, you are completely atrocious at citing any examples beyond the same handful of jazz namedrops, mostly big, popular easy targets that, even in the jazz music world, are well worth criticizing. What's obvious to me is that you still DON'T KNOW S**T about 99% of the people who play improvised music. You have no clue what that scene's been doing and completely rely on a frail set of introverted conservatory stereotypes. You look at other genres in music the way the Nazis looked at Slavic people and homosexuals during the Third Reich. Getting the word "inferior" out of your big stupid mouth is about as easy as getting a white supremacist to utter the 'n' word. I've noticed you puffing out the same stale hot air and tired arguments about jazz for over a year and you still haven't got a leg to stand on.
Why don't you surprise us all and actually cite some musicians that aren't so easy to generalize about. Or at least spare us your worn-out classical posturing and admit that you hate jazz because you're a joyless, hollowed-out failed musician who doesn't know when to give up on a losing argument.
As a matter of perspective, I've met many insanely talented classical musicians and a few excellent composers, and NONE of them ever had a stitch of negative garbage or bile towards the jazz scene or other music scenes. The ones who talk the most trash are always the failures who are angry that they went to conservatory for four years and are still teaching private lessons, always the washouts who couldn't think outside the box and listen to recordings/musicians/genres that weren't shoved down their throats by their a-hole college professors, always the losers who should have never become musicians because they are just using music as an excuse to convince themselves that they're more intelligent than others. Give me a break...
Should classical musicians consider someone like cellist Matt Haimovitz to be some kind of traitor because he's recorded cello arrangements of Jimi Hendrix's 'National Anthem' and played improv gigs with DJ Olive and jazz guitarist John McLaughlin? To put it into more perspective, Haimovitz is a complete genius musician and has recorded almost every important piece in his instrument's repertoire (ranging from the six Bach suites to modern sonatas by Barber, Hindemith, Carter, Ligeti, etc...). When I met the Prism Saxophone Quartet, they told me about some of the amazing jazz composers and improvisers they worked with on a regular basis, and went on to play a stunning set of modern 'classical' pieces by Glazunov, Denisov, Gubaidulina, and Smirnov. Let's be sure that it's damned clear that, in the REAL music world, where musicians actually perform and do meaningful things, any perceived rift between jazz musicians and classical musicians is not even a remote concern. Good, established musicians wouldn't be caught dead indulging in puerile debates about which genre is "harder" or what style is "inferior." Anyone of you who actually feel the need to wave one flag or the other need to get your musical priorities straight.
