George Gershwin's Rhapsody in Blue (1924) is a landmark in 20th-century music. Gershwin drew upon the jazz music enveloping New York City in the 1920s to create the 'American Sound', which would inspire generations of composers in years to come. Josie D'Arby presents the BBC Scottish Symphony Orchestra with pianist Marc Andre Hamelin, conducted by Thomas Dausgaard, performing the piece in full from Glasgow's City Halls. Through conversations with the Dausgaard, Hamelin and members of the orchestra, and interviews with jazz pianist and composer Julian Joseph and broadcaster, critic and biographer David Benedict, the programme delves deep into Gershwin's swinging salute to the city that never sleeps, exploring the composer's desire to be taken seriously beyond Broadway, and the improvisational approach which drew together so many different musical influences to create this iconic and and much-loved piece of music.
