Description: The lecture of Mariella Greil and Martina Ruhsam aims at giving insights into specific collaborative methods that were developed in the frame of choreographic projects – such as the method of reformulation (of the Artistwin deufert + plischke) or the experiment of working together alone of the Cooperativa performativa in Rumania. They touch upon Gesa Ziemer ́s concept of complicity and the issue of self-organisation and put their thoughts in relation to their own artistic practices and collaborative experiences as members of two distinct collaborative platforms: “Sweet and tender collaborations” and “Kollaborateure”. Mariella Greil and Martina Ruhsam work together in difference.
