Donald Romain Davis (born February 4, 1957) is an American film score composer, conductor, and orchestrator. Best known for his work on The Matrix, he has worked on a variety of films, from horror to comedy.
Throughout early life, he found himself interested mainly in the jazz and rock genres. After graduating from high school, Davis enrolled at UCLA. He continued his study of musical composition with tutor Henri Lazarof. Additionally, he learned orchestration from Albert Harris. During their orchestration lessons, Harris introduced Davis to the TV composer Joe Harnell, who supported Davis during his search for work — the first of which being for composer Mark Snow's Hart to Hart, a TV show based on the popular 1930's film series The Thin Man. He also worked as additional orchestrator for Michael Kamen on the film Die Hard 2: Die Harder.
Davis' magnum opus is Matrix trilogy: The Matrix, The Matrix Reloaded, and The Matrix Revolutions. It was set apart from other film scores of its time for its atonality and avant garde style of composition, with influences from polytonal minimalist works like John Adams' Short Ride in a Fast Machine and cluster-like techniques prominent in the works of composer Witold Lutosławski. All three scores garnered wholly positive reviews from critics and fans, and the CDs sold decently.
