How can the complex soundworld of electronic musicians inspire the development of a new vocabulary and tools for describing and exploring the transformation of urban sound environments? Through participation in artistic projects research is conducted into a new evaluation of the transformation of two urban areas which are physically and socially marked by their industrial past. The avant-garde output and experimental collaborations of independent electronic record labels provide the conceptual and methodological basis for a participatory dismantling and redefinition of a collective appropriation of old industrial zones in transition.
