Early in Iphigenia in Splott, the play’s lead character, Effie, looks at the audience and says, “You lot. Sitting back, taking it easy, waiting for me to—what? Impress you? Amaze you? Show you what I’ve got?” Her insolence continues for the rest of the show. Written by Gary Owen, the play is a riff on the Euripides play Iphigenia in Aulis, the ancient Greek drama in which King Agamemnon sacrifices his own daughter to appease the goddess Artemis. Here, the indifferent U.K. government is the patriarch, and the drug and alcohol addicted Effie, partying and slumming in Cardiff, Wales, is the sacrifice. Sophie Melville, who was Effie in the play’s 2016 debut, returns to the role. —Jensen Davis
