The Montreal bass saxophonist Colin Stetson has played sideman to Arcade Fire, David Byrne, Tom Waits and many others. Now, he’s stepping out into the spotlight. With just one saxophone, he uses circular breathing techniques to create a complex, layered sound that is, well, breathtaking. Watch Stetson perform his song "Judges" from his recent release New History Warfare Vol. 2: Judges during a recent stop at WNYC's Soundcheck studios.
