Nuages (Clouds) from Three Nocturnes

Claude Debussy's Nuages (Clouds), second movement of his Three Nocturnes, here expertly transcribed for large brass ensemble by Michael Allen.
 
Debussy biographer, Léon Vallas, recounts the composer's comments regarding the genesis of this piece: "One day, in stormy weather, as Debussy was crossing the Pont de la Concorde in Paris with his friend Paul Poujaud, he told him that on a similar kind of day the idea of the symphonic work "Clouds" had occurred to him: he had visualized those very thunderclouds swept along by a stormy wind; a boat passing, with its horn sounding. These two impressions are recalled in the languorous succession of chords and by the short chromatic theme on the [euphonium]."
