Hans Zimmer, who scored Nolan's The Dark Knight Trilogy and Inception (2010), returned to score Interstellar. Nolan chose not to provide Zimmer with a script or any plot details but instead gave him a single page that told the story of a father leaving his child for work. It was through this connection that Zimmer created the early stages of the Interstellar soundtrack. Zimmer and Nolan later decided the 1926 four-manual Harrison & Harrison organ of the Temple Church, London, would be the primary instrument for the score. Zimmer conducted 45 scoring sessions for Interstellar, three times more than for Inception. The soundtrack was released on November 18, 2014.
