At first, It Folds feels baffling, a blur whose beauty defies close analysis. It blurs the boundaries between life and death, making the ghosts of murdered children walk among their grieving families. It blurs the lines between truth and fiction, drawing on real-life stories of child abduction but muddying their details until they become universal. And most of all, it blurs the categories we place performance into. Its large cast mix dance, physical theatre, matter-of-fact monologues and disconcerting wit into a piece that creates a incense-heady atmosphere of its own.
