The importance of this annual event becomes more and more obvious each year, flying the flag for abstraction and experimentation. It kicks off its 14th season with key elder figures: Billy Bang puts his violin in front of three trumpeters, a trombonist, and the traps of Russell Carter. Douglas Ewart pairs his reeds with other winds, Joseph Jarman’s flute, and Amiri Baraka’s verse. Butch Morris lays a little spontaneous conduction on a feisty string section and a chorus of poets rendering the texts of Allan Graubard. Heady stuff that reminds you why it’s called art music.
