Joan Baez is an American folk singer, songwriter, musician, and activist whose contemporary folk music often includes songs of protest or social justice. Baez has performed publicly for over 55 years, releasing over 30 albums. Fluent in Spanish as well as in English, she has also recorded songs in at least six other languages. She is regarded as a folk singer, although her music has diversified since the counterculture days of the 1960s and now encompasses everything from folk rock and pop to country and gospel music. Although a songwriter herself, Baez is generally regarded as an interpreter of other people's work, having recorded songs by the Allman Brothers Band, the Beatles, Jackson Browne, Leonard Cohen, Bob Dylan, Violeta Parra, Woody Guthrie, The Rolling Stones, Pete Seeger, Paul Simon, Stevie Wonder and many others. In recent years, she has found success interpreting songs of modern songwriters such as Ryan Adams, Josh Ritter, Steve Earle and Natalie Merchant. Her recordings include many topical songs and material dealing with social issues.
