“Musicians like Linda Oh — musicians’ musicians — don’t care that their work isn’t a mass phenomenon; they’re the anti–Taylor Swifts, the un-Beliebers. In that way, they’re countercultural, as were their forebears during Charlie Parker’s and Dizzy Gillespie’s bebop revolution uptown at Minton’s in the Forties, or the Ornette Coleman–led free movement unleashed at the Five Spot in Cooper Square in 1959, or the post-Coltrane howls at Studio Rivbea during the loft era, in the decrepit streets of 1970s Soho. That heat and currency appears to be swirling around the jazz world once again.”
