Braids together three disparate strands--Bob Dylan, Woody Guthrie, and a labor strike in northern Michigan--into one epic saga that holds meaning for working Americans today. Following the trail from Dylan to Guthrie to an event that claimed the lives of seventy-four men, women, and children a century ago, Wolff found himself tracing the history of an anger that has been passed down for decades. Grown-up anger chronicles the struggles between the haves and have-nots, the impact changing labor relations had on industrial America, and the way two musicians used their fury to illuminate economic injustice and inspire change.
