Presented by Tom Service.

This week, Tom talks to the American mezzo-soprano Joyce DiDonato about her life in music, and her creative mission to challenge the status quo. From her work in refugee camps, to her long relationship with the maximum security prison SingSing in New York State, as well as in concert halls and opera stages, DiDonato confounds expectations of an international classical artist. She talks about the joy of engaging differently with young audiences, and of recording and touring projects like Eden, which makes real connections with the natural world and includes the publishing of new music for anyone to sing.

Conductor Edward Gardner and artist Ben Cullen Wiliams talk about their reimagining of Szymanowski's ballet Harnasie: a story of love, bandits, and how the robbers of the Tatra mountains in Poland win out over the civilisation below. Also featuring filmed choreography by Wayne MacGregor, the production has received its premiere in Katowice and comes to London this month, and uses human and digital intelligence to form a kinetic, sculptural video installation opening a portal to new worlds of dance.

And Caroline Potter reveals the mission behind her new book, 'Pierre Boulez: Organised Delirium', which aims to change perceptions about the French composer. A leading figure of the musical avant-garde in the mid-20th century, Boulez is known for the mathematical and structural elements of his music, but Caroline Potter places just as much importance on the influences in his early career from the worlds of literature, magic, surrealism and the music of other cultures.
