The article addresses the role of performative practices in the informal camps and shantytowns in southern Italy, where many sub-Saharan migrants live. In these settlements, creation and performative expressions take various forms: an organic and unplanned one, which gives shape to multiple improvised languages; one supported, sustained, and often directed and managed by associations; and finally, one produced by non-migrant artists who see the camps as a challenging field of research to situate their works. These three forms (of/with/on) bring several critical issues concerning the role played by migrants, the dynamics of appropriation and agency, and the power relations with local associations, professional artists, and political activists, which intersect in complex ways. The article addresses these different artistic experiences, considering strategies of self-representation, artistic legitimacy, and authorship. Finally, it analyses how performative practices become a primary political tool for facing spatial segregation and racial discrimination.
