Ruination begins with an ironic prologue in which a choric figure warns the audience that what follows makes unlikely matter for the festive season: look elsewhere if you’re after light entertainment, he says, because this is going to shake you up a bit. And it does. This is genre-defying physical theatre, ‘devised’ by Ben Duke, in which spoken text is combined with episodes of dance and interludes of song, playfully satirical in tone and uprooted from any boundaries of realism or historical period.
