For the last decade, Justin Vernon’s Bon Iver project has been an inward-looking insular thing, one sad, lonely man singing out to whoever may or may not be listening to him, whether or not he’s singing from Kanye’s Hawaiian Vacation or from his dad’s hunting cabin. But he’s also built a community of like-minded artists and a successful festival (Eaux Claires), and been more open to the world, which hasn’t manifested itself in his music until now: this is the most widescreen, big band Bon Iver album (many, many people contribute here), the work of not just one man, but corralled by him into this new, bigger sound. For these keeping track, this is Vernon’s 4th straight stunner.
