One of the best indie-folk bands, Bon Iver, has been creating great tunes over the past 15 years, garnering Grammy awards and many fans along the way. They've also collaborated with the likes of Taylor Swift, James Blake, Beck and others on their albums. Bon Iver (from the French "bon hiver," or good winter) formed in Wisconsin, where they know "good" winters well enough. Here's "Second Nature", their new release from the soundtrack of the film "Don't Look Up," starring Meryl Streep and Leonardo DiCaprio.
