An anthropologist trained in Nanterre, Corto Vaclav discovered the work of Jean Rouch and developed a passion for Africa and its cinema. He approached the Ethnographic Film Committee, where he worked for two years in a row, allowing him to establish many relationships within this world of explorer-filmmakers whose stories fascinate him. There he met Hadrien La Vapeur, who was looking for a soundman to go to the Congo. Very quickly, his journey transformed into an initiatory and protean exploration. The partners then decided to found the multimedia collection Expedition Invisible to manage their different works.
