In 1969 Loren McIntyre, a National Geographic photographer, found himself lost among the people of the remote Javari Valley in Brazil. It was an encounter that was to change his life, bringing the limits of human consciousness into startling focus.    Inspired by the book Amazon Beaming by Petru Popescu, The Encounter traces McIntyre’s journey into the depths of the Amazon rainforest, incorporating innovative technology into a solo performance to build a shifting world of sound.   The Encounter opened at the Edinburgh International Festival in August 2015 performed by Simon McBurney, and received its London premiere at the Barbican in February 2016 before embarking on a world tour.
