Blood on the Tracks is the fifteenth studio album by American singer-songwriter Bob Dylan, released on January 20, 1975, by Columbia Records. The album marked Dylan's return to Columbia after a two-album stint with Asylum Records. Dylan began recording the album at an A & R studio in New York City in September 1974. In December, shortly before Columbia was due to release the album, Dylan abruptly re-recorded much of the material in Sound 80 studio in Minneapolis. The final album contains five tracks recorded in New York and five from Minneapolis. The album’s songs have been linked to tensions in Dylan's personal life, including his estrangement from his then-wife Sara. One of their children, Jakob Dylan, has described the songs as "my parents talking." In interviews, Dylan has denied that the songs on the album are autobiographical.
