The abstract saxophone drone machine Colin Stetson spent the past couple of years as a touring member of Bon Iver, and Bon Iver frontman Justin Vernon sings on four of the songs that appear on Stetson’s new album New History Warfare Vol. 3: To See More Light. (Preview a couple of those songs here.) Now, Stetson and Vernon have teamed up again, covering “Warm Shadow,” a track from the Bristol singer and multi-instrumentalist Fink. The cover, which turns a tense folk song into space-jazz IDM, shows up on Fink’s new “Warm Shadow” single, and you can hear it below.
