A tour de force of storytelling years in the making: a dual biography of two of the greatest songwriters, Bob Dylan and Woody Guthrie, that is also a murder mystery and a history of labor relations and socialism, big business and greed in 20th-century America - woven together in one epic saga that holds meaning for all working Americans today.

When 13-year-old Daniel Wolff first heard Bob Dylan's "Like a Rolling Stone", it ignited a lifelong interest in understanding the rock poet's anger. When he later discovered "Song to Woody", Dylan's tribute to his hero, Woody Guthrie, Wolff believed he'd uncovered one source of Dylan's rage. Sifting through Guthrie's recordings, Wolff found "1913 Massacre" - a song that told the story of a union Christmas party during a strike in Calumet, Michigan, in 1913 that ended in horrific tragedy.

Following the trail from Dylan to Guthrie to an event that claimed the lives of 74 men, women, and children a century ago, Wolff found himself tracing the history of an anger that has been passed down for decades. From America's early industrialized days, an epic battle to determine the country's direction has been waged, pitting bosses against workers and big business against the labor movement. In Guthrie's eyes the owners ultimately won; the 1913 Michigan tragedy was just one example of a larger lost history purposely distorted and buried in time.

In this magnificent cultural study, Wolff braids three disparate strands - Calumet, Guthrie, and Dylan - together to create a devastating revisionist history of 20th-century America. 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.
