A four-day experience during Artissima 2018. An invitation to build and inhabit an experimental free school in Turin. A stage, a workspace, a thinking place, an archive, a radio station, a recording studio, and an art space. Composed by Jan St. Werner, its coordination is based on collective learning and self-organization, open to participants of all ages and from all countries. DAF Struttura was a light and sound installation that functions as a research and performance environment. For four days, during the Fair, Struttura was a stage, a workspace, a thinking place, an archive, a radio station, a recording studio, and an art space. Its coordination is based on collective learning and self-organization.
