The Museo Nacional Centro de Arte Reina Sofía presents a retrospective of the work of Chip Lord (Cleveland, 1944) a pioneer in video creation in the United States and co-founder of the art and architecture collective Ant Farm, created to map the American psyche of the 1940s and 50s without losing sight of the rapid technological changes of the post-war period. The works done by Ant Farm, whose members (co-founder Doug Michels and Curtis Schreier and Hudson Marquez, who joined later) came from the field of architecture, treated the media in a way that differed significantly from other video collectives in the late 1960s and early 1970s. Decidedly interdisciplinary, the group produced works that combined performance art, media language, sculpture and graphic and architectural design and usually exhibited the countercultural ideology of the era with a free-and-easy sense of humour.
