Two chamber operas by Irish composer Emma O’Halloran, both adapted from plays by her uncle, Mark O’Halloran. The first, Trade, is utterly compelling and deeply moving: the story of two men meeting for sex in a grubby hotel room, whose intertwining lives are burdened by trauma and love. The composer writes of the »beautiful economy« in her uncle’s language and the same could be said of her music, which charges the text with more and more tension and urgency without cramping it – but just as often barely registers at all, letting theatre and storytelling rule. The vocal acting is outstanding.

The stylistic resourcefulness of Trade, in which the two characters are so vividly drawn, returns in the monologue Mary Motorhead but with less success. Here, musical sampling can get in the way of our view of the prisoner, who tells of her troubled life before she split her husband’s head open with a knife. Taken with Trade, though, it only emphasizes O’Halloran’s brilliance with theatre and deft musical hand. Would it be too much to hope for one or two truly theatrical, storytelling operas like these in the avant-garde strand of Copenhagen Opera Festival?
