Does the diversification of mainstage theatre amplify or co-opt marginalised voices? Ilbijerri Theatre Company is one of Australia's only companies creatively controlled by Indigenous artists. We meet their artistic director, Rachael Maza.

Also, we discuss August Wilson's famous The Ground on Which I Stand speech about the need to fund black arts organisations in America and visit the company that developed his first play: Penumbra Theatre in Saint Paul, Minnesota.
