Near Altamira, in the midst of the tropical rainforest, the Rio Xingu, a tributary of the Amazon River, is under pressure from the Belo Monte hydroelectric dam, the third largest hydroelectric dam in the world. Stage director and researcher Gabriela Carneiro da Cunha, has been investigating the effects of the dam on flora, fauna and humans. Her performance instal¬lation provides a platform where ecologists, ar¬tists, and displaced persons can speak up, as can the murmuring river and forest. On stage all the different voices are expressed through the performer as she is transformed into an audiovisual serpent, a particle-accelerating shaman and other high-tech spirits. The combined effect, operating through processes interacting between bodies, LEDs and speakers, plus a video report of the river, takes the audience on a surreal and ceremonial journey, traveling all the way through to the dream of destroying the dam.
