At the age of eight, Auster began to take singing lessons. A year later she had a very small part in a film and by the age of twelve she began acting lessons at Lee Strasberg Theatre and Film Institute.
Auster was sixteen when she recorded her first record. The album was a collaboration between Sophie and Brooklyn based musicians Michael Hearst and Joshua Camp of the musical duo One Ring Zero. Using her writer father, Paul Auster's, early translations of French Surrealist poets, along with two original lyrics written by Auster herself, the poetic lines of Tristan Tzara, Paul Eluard, Robert Desnos, Philippe Soupault and Guillaume Apollinaire became songs set to music by Hearst and Camp.
The collaboration began as a side project Auster pursued after school and on weekends. It was never intended for wide public consumption, but when a family friend heard the album, she was so impressed; she offered to release it under the French label Naïve Records. The album quickly made its way from France into other countries in Europe and beyond. Her subsequent self-titled album is Sophie Auster.
In July 2006 Auster was on the cover of the Spanish issue of Rolling Stone magazine. In 2007, Auster began writing with writer/musician Barry Reynolds, who has worked with Rufus Wainwright, Marianne Faithfull, Antony and the Johnsons, Charlotte Gainsbourg, and Grace Jones. The two have collaborated on many songs together. After graduating from Sarah Lawrence College in 2010 Sophie began recording again. Sophie's self-produced record, "Red Weather", was released November 13, 2012 through Lost Colony Music. Auster's full-length LP, Dogs and Men, was released in June 2015 via Sony Red. "Dogs and Men" came out to rave reviews. The New York Times praised it for its "sultry, folksy vocals" and W Magazine called it "soaring". In 2016 Sophie was a grand prize recipient in The John Lennon Songwriting Contest for her song "Little Bird".
In 2016 Auster began work on her latest album, Next Time, with producer Tore Johansson due out in the spring of 2017.
