“Three Mouth-Light Arrays to Counter Frightful Darkness” is a field guide for executing a series of three outdoor performances, or arrays. The experience is intended for a street corner or road-side. The three arrays involve three performers with lights in their mouths, moving through choreographed formations, which are illustrated in this field guide. A fourth participant may act as a director and documentarian. The performance responds with playfulness to the fear often associated with darkness. I collaborated with graphic designer, Phil McCollam, to create the field guide.
