Bon Iver is the nom-de-guerre of musician Justin Vernon. His album For Emma, Forever Ago was a critical and commercial hit, making him one of the most talked-about indie artists of 2008. For his scores to One A.M. & Easy Street, he’s joined by Chris Rosenau, of Collection of Colonies of Bees, whom Justin calls his “guitar mentor.” Steve Kimock is best known as co-founder and guitarist for the San Francisco band Zero. He’s recorded and performed with Bruce Hornsby and members of the Grateful Dead—Jerry Garcia once hailed him as his favorite guitarist. He performs music for Buster Keaton’s Cops.
