Gone from Danger is a Joan Baez album from 1997.
 Rather than relying on her own songwriting, Baez instead selected work by younger folk and rock artists to perform.
 She included Dar Williams' "If I Wrote You", Richard Shindell's "Reunion Hill", and Betty Elders' "Crack in the Mirror", as well as two Sinéad Lohan compositions.
 Around the time of the album's release, Baez confessed that she no longer found herself able to write songs, and felt more comfortable reverting to her original role, as an interpreter.
 The one track for which she receives credit, "Lily" (about a girlhood friend), was a poem written by Baez, to which Greenberg and Wilson added music.
Paul Frederic Simon (born October 13, 1941) is an American musician, singer-songwriter and actor.
 Simon's musical career has spanned seven decades, with his fame and commercial success beginning as half of the duo Simon & Garfunkel, which was formed in 1964 with Art Garfunkel.
 Simon was responsible for writing nearly all of the pair's songs, including three that reached No. 1 on the U.S. singles charts: "The Sound of Silence", "Mrs. Robinson", and "Bridge over Troubled Water".
Two Can Dream Alone is a compilation album by folk rock duo Simon & Garfunkel.
 The album is a collection of songs from before they recorded their debut album "Wednesday Morning, 3 A.M.".
 It also has solo recordings by both Paul Simon and Art Garfunkel during this era of their careers.
 It contains all of Simon & Garfunkel's singles from these years.
 Six years after its release, a similar album was released which contains all Paul Simon songs except for "Beat Love" by Art Garfunkel, which appears on both albums.
 The songs on that album are also from their early years.
Joan Baez in San Francisco was a demonstration record recorded by the 17-year-old Joan Baez in 1958, released without permission on Fantasy Records in 1964.
 Baez sued to block its distribution and it was withdrawn.
 There have since been authorized releases on other labels.
 It was released by Bear Family Records as A Package of Joan Baez.
"My Little Town" is a 1975 song by the American duo Simon & Garfunkel.
 It was written by Paul Simon, who produced the track along with Art Garfunkel and Phil Ramone.
 Although the song would not appear on any of the duo's albums until later, it was included on both the solo releases for Simon ("Still Crazy After All These Years") and Garfunkel ("Breakaway") in 1975.
 This song was the first new single for Simon & Garfunkel since 1972's single hit "America".
 It became an all-new Simon & Garfunkel reunion single.
Portrait of Joan Baez is a 1967 Joan Baez compilation album, released in the UK.
 It includes material from her early 1960s traditional folk and her Bob Dylan and Phil Ochs covers.
 The album is mono and was released on Vinyl in the UK.
 It features a mix of studio and live recordings.
The Joan Baez Lovesong Album was a 1976 compilation Vanguard put together in their series of Joan Baez reissues, following Baez' 1972 departure from their label.
 This album was a collection of love songs Baez had recorded during her Vanguard years, including traditional and contemporary work, as well as an arrangement of E. E. Cummings' "All in Green My Love Went Riding" by Peter Schickele.
 The cover painting was done by painter and musician Eric Von Schmidt.
Gracias a la Vida (subtitled Joan Baez canta en español), or Here's to Life: Joan Baez sings in Spanish is a 1974 studio album released by Joan Baez.
 It was performed mainly in the Spanish language (just one song in Catalan language).
 Baez stated at the time that she released the album as a "message of hope to the Chileans suffering under Augusto Pinochet", in the wake of the death of Salvador Allende.
 (Baez is known for her criticism of US foreign policy in Latin America, and has toured and worked on behalf of improving human rights in the region).
 Songs include selections by Chilean composers Victor Jara (who was tortured and killed in the aftermath of the 1973 coup d'état) and Violeta Parra, who composed the title song.
Diamonds & Rust in the Bullring is a Joan Baez album, recorded live in the bullring of Bilbao, Spain.
 It featured twelve songs, six of which were performed in English, five in Spanish and one - "Txoria Txori" - in Basque.
 Most of the songs had been performed and recorded by Baez previously, with the exception of Leonard Cohen's "Famous Blue Raincoat".
Joan is a 1967 album by Joan Baez.
 Having exhausted the standard voice/guitar folksong format by 1967, Baez collaborated with composer Peter Schickele (with whom she'd worked on the 1966 Christmas album, "Noël"), on an album of orchestrated covers of mostly then-current pop and rock and roll songs.
 Works by Donovan, Paul Simon, Tim Hardin, the Beatles, and Richard Fariña were included, as well as selections by Jacques Brel and Edgar Allan Poe.
