Input (English): Context_1 : Starsailor is a 1970 album by Tim Buckley (see 1970 in music), released on Herb Cohen's Straight Records label. It marks the moment Buckley's folk rock origins became invisible as he fully incorporated jazz rock and avant-garde styles into his music. Although it alienated elements of his fanbase upon release, it also contains his best known song "Song to the Siren". This more accessible song was written much earlier than "Starsailor"'s newer material, originally in a more traditional folk arrangement, as shown on the later released compilation album "". Bunk Gardner, a former member of the Mothers of Invention, joined Buckley's normal band to record the album. Also, Buckley began working again with lyricist Larry Beckett, after a three-album absence.
