Attend this Chris Davis-booked show, and you can see the saxophonist dubbed the “Johnny Appleseed of Free Improvisation.” That’s as good a term as any to describe the influence Jack Wright has had over the past four decades, convincing collaborators to form their own groups and even sympathetic venues while making music that honors his commitment to community activism. On his website, in the guise of offering three separate bios to suit the needs of various media outlets, Wright sums up an underground musician’s dilemma in trying to get the word out about his music and performances: “Before a musician can actually play in front of others, one must find ways of communicating with listeners and promoters who are quite diverse in their needs and images of what they want. We are selling one breakfast cereal to everyone with a potential taste for it, that’s what the entrepreneur is supposed to do, so we must prepare a variety of packaging. Who is the real person, an established career musician some will trust from critical hearsay, a DIY’er whom others might trust even more, or a charlatan? Can we even guess what the real experience of the music is going to be like?” All the more reason to turn out for Wright’s Nashville return accompanied by percussionist Andrew Drury, with an opening set by multi-instrumentalist and freestyle hand-drummer Noa (the nom de performance of longtime community activist Noa Ben-Amotz). Admission $10.
