Elisabeth Lutyens and Edward Clark were a kind of power couple of the 20th century: she a prolific composer; he a less successful conductor but an influential producer and administrator. Annika Forkert is the author of Elisabeth Lutyens and Edward Clark: the orchestration of progress in British twentieth-century music, and she tells Andy the story of their relationship and their work.

Electronic pioneer Ash Wednesday has had a “self-imposed hiatus” from music over the last decade as he was confronted by a diagnosis of progressive multiple sclerosis. He joins Andy to talk about his new album, AfterMATH, a work for electronics and the majestic Melbourne Town Hall Grand Organ, composed and generated around Ash’s loss of movement in the right side of his body.
