Dan,
I gotta say that I strongly disagree. I, for one, love the fact that Iverson is willing to offer his opinions -- because, after all, that's all anyone has to offer.
Consider: Iverson doesn't groove to Martial Solal -- and Solal is one of my very favorite musicians -- but why in the world should that prevent me from enjoying other things that Iverson has written with which I COMPLETELY agree? For example, see his stuff about Cedar Walton.
Seems like we're picking nits, trying to find points of contention. There's no one in the world whose idea of jazz is just like mine -- or yours -- or his. Our conceptions of what constitutes "good" or "interesting" jazz are like Venn diagrams. Some have more overlap than others, but NONE are the same.
So why get wrapped around the axle when there are differences in points of view when the differences are absolutely inevitable and even essential?
I guess I feel like the dialogue itself is more important than the particulars of the dialogue!
Or at least that's how I like to think about it.
