What exactly it was, and this show is, is sworn to secrecy, as the whole performance – in which the audience is taken on an interactive ‘ride’ manned by a 200-strong cast – relies on surprise for its liberating, sense-defying effects.

Beg, borrow or steal, if needs be, to be a part of Kate Bond and Morgan Lloyd’s (above) sensory-assaulting 45-minute experience.

Until Sept 19. 7pm-10.45pm, every 15 mins, £20
