One of West Africa’s leading visual artists, Romuald Hazoumé has worked with many media throughout his career, from discarded petrol canisters, oil paint and canvas, to large-scale installation, video and photography. As the British Museum presents the UK premiere of his major work La Bouche du Roi, Hazoumé talks with Christopher Spring, artist and curator of the Museum’s African Collections, about the people, ideas and materials that have shaped his extraordinary career.
