Indigenous Australian didgeridoo virtuoso William Barton performs live

Theatre producer Nica Burns, who has run the Edinburgh Comedy Awards since 1984, and judge Ashley Davies discuss the acts shortlisted for this year's prize, the most prestigious annual award for comedy in the UK, which has previously been won by the likes of Steve Coogan, Jenny Eclair, The League of Gentlemen and Tim Minchin.

The founder of theatre company Complicité, Simon McBurney, who himself won that award back in 1985, joins us in the studio to talk about Figures In Extinction, a collaboration with Nederlands Dans Theater and acclaimed choreographer Crystal Pite, which addresses urgent questions about climate change.

Writer and performer Edgar Jacques of Teater Cego in Brazil and actor and stand-up comedian Jasmine Thien discuss their theatre productions - Another Sight and I Dream In Colour - which draw on their experiences of blindness.

And ahead of a performance at the Edinburgh International Festival, indigenous Australian didgeridoo virtuoso William Barton performs live in the Front Row studio.
