Klein embarked on writing Woody Guthrie driven by a profound interest in folk music, which he describes as "a primitive tradition, carried through the ages by common people who wished to express their joy and anger and frustrations through music." At the time, there was a noticeable absence of a comprehensive biography of Woody Guthrie. By the late 1970s, shifting political landscapes in the United States opened the door to crafting a biography that could candidly explore both Guthrie's political and personal dimensions without restraint.

Woody Guthrie serves as a pivotal work in reshaping the popular narrative of Guthrie, often romanticized as the quintessential hobo—drifting across the country, hopping on boxcars, and briefly settling in towns to pen folk songs with social commentary. Klein dismantles this myth, offering a nuanced portrayal that delves into Guthrie’s multifaceted personality. This comprehensive biography captures his leftist political beliefs, his blunt humor, and his remarkable talent for songwriting, alongside his less glamorous traits, such as his voracious sexual appetite and questionable personal hygiene.

For young adults interested in tracing the origins of music with a social conscience, Woody Guthrie becomes an essential read. Guthrie’s life and work illuminate the cultural expressions of ordinary people, bringing attention to their struggles and triumphs through music. Moreover, for budding artists seeking inspiration, Guthrie stands as a testament to pursuing one's artistic vision. He was an individual who engaged deeply with the world around him, translating his observations and experiences into profound artistic expressions.
