As a teenager in the late 1950s, Joan Baez became the leader of the popular folk music movement on the strength of her voice and her repertoire of traditional songs. She's well-known for introducing Bob Dylan to the world in the early ‘60s. But she also remained an advocate for folk music and political change for the next four decades. She joins us to talk about teaming up with songwriter-producer Steve Earle for "Day After Tomorrow," her first studio release in five years.

Joan Baez appears tonight at the 92nd St Y in a conversation with music critic Anthony DeCurtis. She performs at Town Hall on Oct. 28 and 29.
