Can we talk about black theatre?

guardian.co.uk: "It's an interesting time for black theatre in London at the moment. Stop. Rewind. Is that actually a useful thing to say? This is the question posed by the playwright Bola Agbaje on the Facebook group for her Olivier Award-winning play Gone Too Far!, which returns to the Royal Court in July as part of its Upstairs Downstairs season. The discussion topic 'If a black person produces something such as a play, a film or music should it be associated with the word black?' has received almost 4,000 words in reply, passionately arguing both for and against, while examining the wider issues that surround the question."
