Dias & Riedweg includes Mauricio de Mello Dias (b. 1964, Rio de Janeiro, Brazil) and Walter Stephan Riedweg (b. 1955, Luzern, Switzerland), who have worked together since 1993 to make collaborative and interdisciplinary public art projects, videos, and performances.

Dias & Riedweg combine video, ethnography, and performance art to tackle social and political issues; in their projects, the artists examine human subjectivity as it is conditioned by ideas of nationhood and mediated by contemporary technology. Based in Rio de Janeiro, the duo often looks to the conditions of that city’s favela cultures to consider how a city is constituted. Much of their production is based upon social exclusion. Using the tools of both documentary and fiction, the duo make works which narrate experiences of social alienation and distance.
