The works of Claude Debussy (1862-1918) had a major impact on the music of the 20th century, influencing a range of figures from Ravel and Stravinsky to Henri Dutilleux and Toru Takemitsu. Less well known is Debussy's influence on the popular culture of the period. Matthew Brown shows how Debussy's music has surfaced in an array of contexts from the film music of the 1940s to the dance music of the 1990s. It is easy to see how Debussy's impressionist soundscapes for orchestra such as La Mer and Iberia could be perfect models for accompaniments to film scenes, but as Brown makes clear Debussy's music and influence cannot by reduced to dreamy imitations of Clair de Lune. As he traces the trajectory of Debussy's stylistic evolution, Brown shows how facets of this style were reinterpreted in a surprising variety of popular musical contexts.
