Multi-instrumentalist and composer Colin Stetson usually is associated with the avant-garde edge of whatever he’s doing. And he’s doing plenty, running the gamut from jazz to rock, pop, classical, and experimental in numerous contexts, collaborating with everyone from Arcade Fire to Tom Waits, Bon Iver, and Laurie Anderson. He’s considered an innovative virtuoso and daring soloist on reeds, especially the massive bass saxophone, and is equally audacious as a writer and bandleader. At the Walker, Stetson and a 12-piece ensemble will tackle a “re-imagination” of Polish composer Henryk Górecki’s Symphony No. 3, known as Symphony of Sorrowful Songs. It’s a modern classical monster best known from the best-selling 1992 London Sinfonietta/Dawn Upshaw version and numerous film scores. Stetson replaces the original orchestration with guitars, keyboards, drums, and horns, while his sister, mezzo-soprano Megan Stetson, handles vocals. Stetson’s version opens up significant new dimensions in a wrenching dirge dense with devastating anguish. Besides extending emotional boundaries, his classical reinvention flirts with a sometimes startling post-rock realm of industrial noise, drone, metal, free jazz, and electronica.
