Even though Chicken Wire Empire—a bluegrass band that’s been the subject of an hour-long film and who have shared the stage with the likes of Yonder Mountain String Band and The Big Wu—have little left to prove, the group didn’t waste any time before making good on their New Year’s resolution when they released their first record in more than four years, What Moves Mountains, on January 1. At the tail end of a year that featured that long-awaited follow-up and will culminate with a tour in Germany, Chicken Wire Empire hold down The Back Room @ Colectivo for a two-night residency.
