Bon Iver'sBon Iveris Justin Vernon returning to former haunts with a  new spirit. The reprises are there – solitude, quietude, hope and  desperation compressed – but always a rhythm arises, a pulse vivified  by gratitude and grace notes. The winter, the legend, has faded to  just that, and this is the new momentary present. The icicles have  dropped, rising up again as grass.
