Video documentation of Puerto Rican experimental dance performance ¡Uy! -- Opera de Terror, choreographed by Viveca Vázquez and performed in the University of Puerto Rico, Recinto Río Piedras. ¡Uy! explores the concept of offering an opera not with voices but with bodies. There is an operatic counterpoint between frightening music and bodies that seem to be lost; between showing and hiding; between light and shadows; and between movements and immobility. These bodies are literally moving in the edge, verging on the unbalance; in this manner, horror seems to be more a state of the body that a state of mind. The stage is divided based on the different rooms that a house can contain -- in this manner, this performance is related to the space as a concept, and to an exploration of memory, fear, and being afraid of fear. ¡Uy! proposes several questions: What is that which scares us? Our surroundings? Or the objects with which we interact in our everyday life? What is our relationship with our own body? How and when does the body die? How are death and horror related to the death of the body as a corporeal reality?
