This episode is dedicated to American composer, pianist and band leader Duke Ellington (1899-1974). We pay him tribute by listening to his compositions interpreted by various artists including McCoy Tyner, Nancy Wilson, Ben Webster, Carmen McRae & Betty Carter and Weather Report. We also remember Barry Harris, whilst the album of the week is 'Absence' by Terence Blanchard. Duke Ellington photo by Bettmann/Getty Images.
