Gershwin’s An American in Paris – a giddy, gloriously tuneful musical evocation of 1920s Paris – takes a stroll through the bustling City of Light, swept along by the jazz rhythms that were its throbbing pulse. The rhythmic impulse continues through Messiaen’s hypnotic orchestral love song, the Turangal?la Symphony. Premiered by Leonard Bernstein in 1949, this Tristan and Isolde-inspired work is a celebration of sensual pleasure and boundless ecstasy.
