Grupo de Arte Callejero (GAC), Group of Street Artists, formed in 1997 out of a need to create a space where the artistic and political could be collectively reappropriated as a single means of production. Their work blurs the boundaries between militancy and art and develops confrontational forms and strategies that operate within determined contexts: the street, the occupation, the demonstration. From the beginning, their work has searched for a space for visual communication that escapes the traditional circuit of exhibition and exploitation, taking the appropriation of public spaces as its central axis of production. A large part of their work is anonymous in character, which allows for the continued elaboration of these practices and methodologies by like-minded individuals or groups. Many of their projects have emerged as collective constructions with political movements, groups, and individuals, creating a unique dynamic of production that is in permanent transformation due to this constant exchange and putting into political practice.
