Since she began her legendary residency at Boston's famed Club 47 and her debut at the 1959 Newport Folk Festival Joan Baez has remained a musical force of nature whose influence is incalculable - marching on the front line of the civil rights movement with Martin Luther King, singing on the first Amnesty International tour, standing alongside Nelson Mandela when the world celebrated his 90th birthday in London's Hyde Park. Her earliest recordings fed a host of traditional ballads into the rock vernacular, before she unselfconsciously introduced Bob Dylan to the world in 1963 and focused aware­ness on songwriters ranging from Woody Guthrie, Dylan, Phil Ochs, Richard Fariña, and Tim Hardin, to Kris Kristofferson and Mickey Newbury, to Dar Williams, Richard Shindell, Steve Earle and many more.
