CRAC Valparaiso is a collaborative non-profit platform that focuses on different socio-artistic productions over the city of Valparaiso, Chile. CRAC is an independent project with a flexible and autonomous management model that has been self-sustained since 2007. It is a centre for residencies aimed to artists and researchers. The residents are open to experiment with temporary actions that will directly involve the local community such as talks, workshops, performances, seminars and so on. The artistic residencies to be developed at CRAC are understood as city practices and methods of public presentations and workshops that feed and activate our archive which is based on cultural exchange of knowledge. Beside the residency program, they offer access to a public community archive with a printed publication and a digital publisher. Their approach is to rethink from a Latin American city what public art means in relation to other cities. They have worked with a number of different platforms, groups, artists and researches that encourage decentralised collaborative practice.
