Artists collective created in 1993 by Mauricio Dias (Rio de Janeiro, Brazil, 1964) and Walter Riedweg (Lucerne, Switzerland, 1955). Since then, they have presented collaborative projects of public art, video and performance. Dias studied at the School of Fine Arts of the Universidade Federal do Rio de Janeiro and at the Schule für Gestaltung Basel, Switzerland; and Riedweg at the Musikakademie, Lucerne and at the Accademia Teatro Dimitri, Verscio, Switzerland. Their work addresses social and political issues through video, ethnography and performing art. Their aim is to show how contemporary subjectivities are strongly mediated by technology and historical notions such as the idea of a motherland. Whether in projects focused on the shantytowns of Rio de Janeiro or on groups of migrants in metropolitan contexts (such as their ethnographic study in Barcelona's Ciutat Vella), they reveal processes of social exclusion. Using the tools of documentary and fiction, they narrate experiences of alienation and distance.

Since the mid-1990s, they have had numerous exhibitions in European and American cities, such as at the Kunsthalle Oslo, 2008; Americas Society, New York, 2009; Museo Universitario Arte Contemporáneo, Mexico City, 2010; Centro Municipal de Arte Hélio Oiticica, Rio de Janeiro, 2012; Kuntsmuseum, Lucerne, 2017; Museo di Arte Contemporanea, Rome, 2017. Their work is included in the collections of Centre Georges Pompidou, Paris; Museo Nacional Centro de Arte Reina Sofía, Madrid; Museum of Fine Arts, Houston; Museu Nacional de Belas Artes, Rio de Janeiro; Kunstmuseum, Lucerne; and MACBA, Barcelona, among many others.
