Somewhere in a busy city, a man wakes to discover he has forgotten his life. He has no memory of the past and no clear sense of the present. He is concussed. Or so he is told by a doctor -- who may also be his partner. Now there are flashes of something. Hunger, mourning, sexual appetite...Bob Dylan? But why isn't he in hospital? And what of the voices, the Blackberry, the brothers? The hammer? A comedy with attitude, "Concussion" explodes a simple conceit and scatters its achingly funny and filthy tales of the city like shrapnel. (13 acts, 4 male, 2 female).
