For over two decades, Grupo de Arte Callejero has participated in the wave of denunciations of genocide and disappearances during the military junta, the social rebellions of the 2001 financial crisis, neoliberal austerity plans, teachers’ strikes, and Indigenous protests. A critical reflection and collection of their work, Thought, Practices and Actions offers profound insight into what was done and what remains to be done in the social fields of art and revolution.
