The new single from Bon Iver's Colin Stetson, 'High Above a Grey Green Sky', is as suspenseful as productions get. Subtle moans come in and out of a crazed electronic background, waiting any second to break loose. This is off the last album of his New History Warfare trilogy, To See More Light, which was recorded in single takes. Justin Vernon even provides vocals on four of the album's tracks, including this. The album will be out April 30th on Constellation. Head to Soundcloud for a listen and download.
