Colin Stetson + Justin Walter

You may have seen saxophonist Colin Stetson playing with the touring lineups of acts like Bon Iver, Arcade Fire and the National—apparently circular breathers are a hot commodity in indie rock. As a solo artist, Stetson is known for coaxing otherworldly sounds out of his woodwind, such as the rhythmic groans and squawks that populate his latest album, All This I Do For Glory. During this Pitchfork Music Festival aftershow at Constellation, he'll be joined by Justin Walter, who performs with a rare, wind-controlled analog synthesizer.
