On the day this episode is released, the American composer Philip Glass celebrates his 89th birthday. In a career now lasting well over five decades he has somehow achieved two extraordinarily rare things for a contemporary composer of classical music... a prolific amount of creative output and a degree of broad popularity. For the next hour and a quarter please enjoy a quick survey of five decades of great music… films, operas, concertos, quartets… and an unfairly small section of solo piano music. Happy Birthday!
