Songwriter Justin Vernon's debut album as Bon Iver, For Emma, Forever Ago, was about as stark and minimal as records get. With his second album, simply titled Bon Iver, he's gone in the opposite direction. The disc's first single, "Calgary," is full of rich sonic detail, from dreamy synthesizer washes and rumbling percussion to gnarly distorted guitar and assorted bits of noise. Despite all the changes, his band's essential appeal remains the same – it's still all about Vernon's gorgeous, understated voice and his skill for nailing a particular, deeply resonating sort of melancholy. The album will hit stores on June 21st, but you can stream and download "Calgary" today.
