Staying steadfast to her mission, Joan Baez should be the world's bravest singer. In 1967, she and her mother were jailed for over 60 days because she was at the forefront of protesting against America's involvement in the Vietnam War and racial discrimination. Born in 1941, Baez gained commercial success as a folk singer with her first two albums in the early 1960s. From the mid-60s, the singer - half Mexican and half Scottish - became a peace and civil rights activist, writing and recording many political songs which condemn violence and wars.
