British Theatre Guide podcasts
Described as "the leading independent website on British theatre", here is a link to their series of podcasts interviewing cast and production teams, many conducted by David Chadderton (a Rose Bruford tutor). The podcast archive goes back to November 2012.
Theatre Voice Let's talk about theatre
Audio content about British theatre, and features journalists from across the UK press and practitioners from across the theatre industry. It was set up in 2003 to see if theatre could be talked about in a new way: allowing critics to be more expansive than the usual space constraints of the print media allowed; to enable actors, writers, directors and designers to be heard talking in detail and at length about their work; and to help members of the public interact more directly with theatre-makers and commentators.
Theatrevoice was established by Dominic Cavendish (founding editor), with the close support of David Benedict and Rachel Halliburton, as well as Aleks Sierz (co-editor since Sept 2006) and Mark Shenton.
