La Casa Encendida presents El gran silencio, a video installation by Allora & Calzadilla.

Through a wide-ranging exploration of sound, the film examines the irreducible relationships between the living and the non-living, the human and the animal, and the terrestrial and the cosmic. It focuses on Arecibo Observatory, the world's largest single aperture radio telescope, located in Esperanza, Puerto Rico, which transmits and captures radio waves to and from the farthest edges of the universe. The site is also home to the last wild population of critically endangered Puerto Rican parrots, amazona vittata, which have their habitat in the surrounding Rio Abajo forest.
