Odetta Holmes, known as Odetta, was an American singer, often referred to as "The Voice of the Civil Rights Movement". Her musical repertoire consisted largely of American folk music, blues, jazz, and spirituals. An important figure in the American folk music revival of the 1950s and 1960s, she influenced many of the key figures of the folk-revival of that time, including Bob Dylan, Joan Baez, Mavis Staples, and Janis Joplin. In 2011 Time magazine included her recording of "Take This Hammer" on its list of the 100 Greatest Popular Songs, stating that "Rosa Parks was her No. 1 fan, and Martin Luther King Jr. called her the queen of American folk music."

The American folk music revival began during the 1940s and peaked in popularity in the mid-1960s. Its roots went earlier, and performers like Josh White, Burl Ives, Woody Guthrie, Lead Belly, Big Bill Broonzy, Richard Dyer-Bennet, Oscar Brand, Jean Ritchie, John Jacob Niles, Susan Reed, Paul Robeson, Bessie Smith, Ma Rainey and Cisco Houston had enjoyed a limited general popularity in the 1930s and 1940s. The revival brought forward styles of American folk music that had in earlier times contributed to the development of country and western, blues, jazz, and rock and roll music.
