Starting from a bibliographic gap about people who intervene socially through and by the arts, without an academic canon, the sociology of culture and the sociology of the arts intersected in a work of sociological investigation. This crossing is the inspiration for the artists' singular biographies, to consider the social journey of the individuals as the explanatory/interpretative variable of their modes of social intervention by the arts. Throughout the construction of four life stories, we try to understand how ethos and practices simultaneously configure social interventions by the arts, namely through do-it-yourself (DIY) spaces, daily creativity, and identity resistance strategies. What are the common characteristics among these social intervention agents? What predispositions, challenges and proposals can we present? That is how we try to contribute to its conceptualization and recognition.
