Lox, you don't get the point.

Jazz has not changed uniformly. There are many different forms of it being played today, some of them nearly indistinguishable from what Armstrong was doing in the 30s, others using electronic techniques and material from other cultures in ways that were not possible until this millenium. Pine represents a moderately modernist tendency, the big new thing of 25 years ago.

For somebody outside the jazz scene and just listening to the stuff, there is no obvious reason why these different subgenres shouldn't all coexist. (I'm quite happy to listen to both Sid Phillips and Anthony Braxton).

But there is a reason why they shouldn't if you're DOING jazz. You will be competing for funding and gigs with everybody else who labels themselves as a jazzer. And there is a LOT of money at stake - far more public money is thrown at jazz than at anything called "folk" or "trad" (in Scotland anyway, and I doubt if England is any different). Pine's position is not that of a disinterested critic, he has a financial stake in marginalizing competing subgenres (like the 1950s neo-trad subgenre which is maybe the UK's most distinctive invention in jazz so far, or the dance/electronica movement which gets both the largest audiences and the least coverage from "official" jazz media). So he has to say that jazz has moved on as a whole from what Armstrong was doing - in the teeth of the obvious fact that for many players out there making a living at it, it hasn't - they can do just fine while ignoring the post-bebop harmonies that Pine uses, never bothering with laptops, and making no effort to learn any Arabic rhythms.

And I do see a parallel here. Somebody who claims that traditional music doesn't exist any more (with preposterous bullshit rhetoric like sticking to rigid definitions, like the 1954 stone tablet from God delivered unto the great mudcat on mount sinai is absolutely absurd) is lying, just as Pine is, and often for the same reasons - there's money in getting people to believe that. (But not very much money, which makes the attempt look a bit daft).
