Warm Valley is a Duke Ellington composition that appears as the title track on Art Farmer's 1983 jazz album Warm Valley. The album was recorded in September 1982 in New York City and released by Concord Records, running 39 minutes and 4 seconds. It features Art Farmer on flugelhorn with Fred Hersch on piano, Ray Drummond on bass, and Akira Tana on drums. The program mixes Ellington's piece with other standards in a lyrical bop style, and is praised by critics; Scott Yanow of Allmusic called Farmer's performance prime and equal to his earlier Concord sessions. A story circulating on SoundCloud claims Ellington wrote Warm Valley while traveling through Oregon on his private rail car.
