The Sound of My Voice

This revival of an acclaimed two-hander from the Citizens Theatre has lost little of its power. Adapted from Ron Butlin’s novel by director Jeremy Raison, it tells the story of a biscuit company executive’s descent into alcoholism. The punishing drinking sessions and personal and professional nadirs eventually become nauseating to watch. Nicely performed by Billy Mack and Michele Gallagher, this is a dark and powerful piece of entertainment.
