Great to hear the first person perspective. The "freedom to" aesthetic always struck me as a fundamentally post-60's thing. This is why we still need an analytical study of 70's jazz, as the blogosphere has been talking about for something like a decade now--the AACM, BAG, the downtown NY scene, the English free improvisers, the Blue Notes, etc. etc. were playing a very different and much more conceptually complicated music than the early wave free jazz musicians. It's interesting that the Blue Notes get slotted into free jazz on the one hand and European free improv on the other--the former is in respects the "last part" of the bebop continuum, which is why it's so tethered to bop's conceptual devices (theme-solos-theme, soloist/rhythm section divide, frequent presence of metered improvisation, and so on), and music that is categorized as EFI is often more involved in "total" improvisation than American free jazz. The members of the Blue Notes played some free jazz, played some EFI, but their music together is ultimately something else entirely. Of the handful of masters I've spent some time with, the musician whose aesthetic comes closest to absolute "freedom to" is Fred Frith. It wasn't until talking to Frith--at a time, incidentally, when I'd been consumed with listening to the Blue Notes and confronting my own issues as a composer--that I came to realize just how many different ideological camps so-called "creative" and/or "free" music encompasses. Part of Frith's pedagogy involves looking at the materials with which we construct an improvisation--why not play something tonal? Why not play something metered? (And any number of opposites thereon--it's a pretty contrarian philosophy, which is kind of fun.) Playing idiomatic material in a free improvisation still sounds to me like a pretty radical prospect, essentially because idiomatic material forcefully recontextualizes everything around it. The Blue Notes had such a strong shared language that they were able to create music that is simultaneously open to free association and deeply enmeshed in South African culture. I think it's still going to take some time for us to realize just how radical the Blue Notes were, and why we should be evaluating their music in the same hallowed tones we reserve for 60's Don Cherry, the Art Ensemble, and staggeringly few others. and it's posts like these two that make me glad I hang out around here. Insightful, articulate and thought provoking, thanks both. Keep them coming.
