Rhapsody in Blue / An American in Paris is a recorded pairing of orchestral works by American composer George Gershwin, composed in 1924 and 1928 respectively. The pieces blend elements of jazz, blues and European classical form with orchestral colour, syncopated rhythms and jazz-inflected harmonies, representing Gershwin's efforts to bridge popular and concert music and marking significant developments in early 20th-century American musical history.
