Has someone imposed a speed limit on jazz?

Last night, I went to the Wednesday night jazz concert series at the Sacramento waterfront. I must say that there's nothing so pleasing as a ride down the American River bicycle trail and into Old Sac to see a modern jazz great at a small, open-air venue. Last night, it was the Charlie Hunter trio on hand.

Granted, Charlie Hunter is a phenomenal guitarist of supremely developed skill. However, as I was listening to the music, I noticed something that has nagged at me for some time. That is, I found the music to be rather uninspiring, as if set on cruise control. I kept wondering, as I do often, if someone has imposed a speed limit on jazz? Or for that matter, on a lot of artistic expression of late?

As I listened Charlie Hunter and his gifted drummer and sax player trade off the spotlight, and each wade through a somewhat syrupy display of unemotional playing, I just kept thinking of what it might sound like with Al DiMeola, Sonny Rollins, and Jack DeJohnette up their in place of these three. Not that those jazz legends are even my favorites at their respective instruments. It's just that they always pushed the music.

Am I simply confused because jazz is a misnomer for today's music? Because I see something similar in art, and in language as well. It's as though artistic expression has become an exercise in puzzle assembly, where a palatable end is defined even before the process begins. I mean, 30 years after Black Sabbath and Led Zeppelin, do we honestly believe that White Stripes--as a reconstitution of both--stands at the front of the current revolution in rock? Or that Joshua Redman and Dave Koz have sparked a new view of the sax in the way that Lance Armstrong has forced other riders to explore new training methods for professional cycling?

I'm not posting this in order to bash anyone. Rather, I just wanted to share my thoughts, and to get some feedback from other members. Perhaps I'm missing something here. Or maybe we're truly seeing the limits of the expansion of the artistic balloon, and are waiting for it to explode once again. For me, it can't come soon enough.
