As exciting as the term sounds, a supermoon is a fairly common occurrence, an illusion caused when a full or new moon happens to coincide with the moon’s closest approach to Earth. Basically, it means the moon looks a bit bigger than usual. While that might not seem significant to most people, it’s the type of phenomenon Sean Carey pays close attention to. Even more so than his brother in flannel Justin Vernon, whom he backs in Bon Iver, Carey syncs his music to the rhythms of nature. His writing process frequently involves hiking or fishing, and in his spare time he photographs mountainous terrains and forests, likening the images to his songs. Yet for all his wilderness worship, there’s often been a disconnect between Carey’s naturalistic mindset and his production-heavy recordings. Both of his albums were pieced together from meticulous overdubs, while his 2012 Hoyas EP pulsed with electronic texture. His songs sought to capture nature’s warmth, but they wore the stamp of cold technology.
