Kate Molleson talks to Scottish writer and poet Jackie Kay about the extraordinary life of the pioneering blues singer Bessie Smith, and asks what Bessie's blues can tell us a century on.

Kate also hears from American composer Meredith Monk about the recurring nature of the big themes of her work, from plagues to dictatorships, and we hear about the piece she’s currently working on, Indra's Net – 10 years in the making and a work dedicated to humanity’s relationship with nature.

Plus, as part of the BBC's 'Soundscapes for Wellbeing' project, we look at how natural and musical soundscapes can affect mental health, including a groundbreaking study by the University of Exeter called 'The Virtual Nature Experiment', which explores how digital experiences of nature might impact wellbeing. Kate is joined by Alex Smalley from the University of Exeter, the sound recordist Chris Watson, and composer Nainita Desai.
