A book I'm currently reading, "Playing Changes" by Nate Chinen, is a fascinating argument that we are currently in an age of amazing new jazz artists and an equal amount of amazing innovation and new ways for jazz composers and soloists to further this resilient art of musical improvisation. The premise is not one I'd bicker with--ours is a time when the "jazz is dead" club needs to just be silent for a very long time and listen to the creativity that abounds. But, as the review points out, author Chinen, a critic with a forward-thinking preference for new and temperamentally sounds, writes in a such a way that he makes you think of the guy who must have been the least interesting student in a seminar on post-modernism. He does not, as the reviewer suggests, at times sound like Derrida; rather, he seems more like a person who thinks he sounds like Derrida. Which is a shame, because although Chinen writes about important artists and at times makes crucial distinctions in what is happening in the ever-evolving jazz timeline, it seems that the premise of the book is that the music exists only to be co-opted and made to dance between inscrutable phrases and descriptions that don't really intrigue a reader to actually go out and purchase some of this fine new music. Tellingly, Nate Chinen chides the older critical establishment, those who would have jazz become a formalized canon, set in place, with boundaries and inflexible boundaries, yet he seems to be working to construct his own fiefdom of critical imperative. Meet the new boss...In any case, all this begs the question to be asked, which is why can't there be a working idea of jazz that doesn't require anyone going to war against other schools of thoughts on the music, or specific ways of playing. A jazz fan can enjoy both and not be betraying whatever "true spirit" of jazz the critical camps think. Seriously, one occasionally feels that some critics, whether Leonard Feather , Amiri Baraka or Nate Chinen, despite his protest to the contrary, wish they could be in the studio, instructing the musicians in what their note selections and points of creating tension and release should be.
