Bon Iver‘s Justin Vernon is in Iowa tonight stumping for Bernie Sanders and helping to get people out for the Iowa caucus early next week. He performed a set at the Bernie 2020 Caucus Concert, a 45-minute solo acoustic set with a smattering of songs throughout his career and a wonderful poignant “The Times They Are A-Changin'” by Bob Dylan to close the set.

You can watch his full solo set below (it starts around the 1:30:00 mark).
