John Zorn, NY jazz-weirdo par excellance, puts out what can only be called, by anyone's measure, a brutal amount of music per year. Not being content with filling your ears with sound and putting out others' music on his own label tzadik, in 2000 he started publishing the Arcana book series (also on tzadik
Welcome to Tzadik).
Currently it's up to Volume VIII and the website says 250 musicians have contributed (this feels like an exagerration but I haven't counted so IDK). Even a partial list of the contributing musicians who've written pieces for Arcana is like an avant-garde who's-who:
Bill Frisell, Fred Frith, Eyvind Kang, Ikue Mori, Larry Ochs, Bob Ostertag, Mike Patton, Marc Ribot, Elliott Sharp, John Zorn,
Z’EV, Trevor Dunn, Yamataka Eye, Jim O’Rourke, Trey Spruance, J.G. Thirlwell, Sean Lennon, Buzz Osbourne, Derek Bailey, John King, Nels Cline, Bob Ludwig, Pauline Oliveros, Terry Riley, William Breeze, Yusef Lateef, Genesis Breyer P-Orridge, Thurston Moore, Pat Metheny (more that I have left off are on tzadik's website).
Some pieces are legit eye-glazing borefests that remind you that writing is not a gift
that everyone can say they have. But largely these are all well-written pieces, if sometimes disparate. Ben Goldberg's piece is technical and requires at least passing familiarity with written music:
Trey Spruance (Mr Bungle, Secret Chiefs 3, Faith No More, etc) has a piece in the second volume that veers from rumination on audience into....this....weirdass script...featuring characters (no surnames but....) such as GG, Kurt and Bon Scottus Eurigena.
Foetus' piece on tinnutus is interesting, more about practicalities and the meat and potatoes of being a working musician:
If these appeal to you, FYI they are part of Target's "buy 2 get 1 free" sale
