Tom Service takes on the largest instrument created by human hands: the organ. With the help of organist Anna Lapwood, Tom asks: what makes the organ so mighty? Why has it fascinated musicians from Bach to Procol Harum? Along the way, Tom will delve into the Delphian roots of the organ and we’ll hear what its ancestor the Hydraulis sounded like, created in ancient Egypt. And we’ll drop in on Madison Square Garden where Gladys Gooding entertained huge audiences at sports events for over thirty years, starting in the 1930s. Finally, we’ll hear what makes the organ timeless and immortal in music by John Cage and Olivier Messiaen. All hail: the organ!
