"Odetta Holmes known as Odetta, was an African-American singer, actress, guitarist, songwriter, and a human rights activist, often referred to as "The Voice of the Civil Rights Movement". Her musical repertoire consists largely of American folk music, blues, jazz, and spirituals. An important figure in the American folk music revival of the 1950s and 1960s, she was influential musically and ideologically to many of the key figures of the folk-revival of that time, including Bob Dylan, Joan Baez, and Janis Joplin." -From Wikipeida
