The Proa Foundation presents, through August 24th, Acción Urgente, a South American panoramic of art interventions in urban spaces from the 1990s through the present. The show, curated by Cecilia Rabossi and Rodrigo Alonso, features works by a number of collectives from Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay, who take the city as their stage and support. The exhibition includes records of urban interventions carried out by artists working in multiple disciplines, who, interpellated by political, social, and economic realities, set in motion art actions intended to give visibility to issues such as women's rights, political corruption, impunity, racism, ecology, and indigenous rights, among others. Photographs, videos, objects, and interventions in the gallery reconstruct the history of each of the groups and the art actions they carried out. Veritable meaning guerillas, these artists leave the museum behind and take over the streets, buildings, public squares, trees, and monuments; any urban object or location can be susceptible of reutilization in provisional, ephemeral ways in order to expose, critically, their concerns and demands. The actions and performances included in this exhibition offer a survey of contemporary artistic expressions that confront reality critically, taking the urban space as material for action and expression.
