Mathieu Tremblin, member of the “Frères Ripoulins” and Epos 257, respectively invited at the “Bien Urbain Festival” in 2014 and 2015, realised a series of spontaneous actions. Investing the outdoor space of abandoned shops by installations, performances or changing urban codes, their interventions question us about our relationship with consumption society, publicity or nature. Project created within the scope of the “8th Bien Urbain edition”.
