At the end of our HTA lecture series “Collaborations, Cooperation, Collectives – In/Stable Working Conditions in Art and Institutions”, we take a closer look at concrete artistic practices of collaboration. For this we have invited three representatives of three collectives and ensembles from the Frankfurt/Rhine-Main region: Katharina Pelosi, Katharina Stephan and Susanne Zaun. The Swoosh Lieu theatre machinists, as they describe themselves, use light, sound and video to artfully transform the theatre space into a place of joint negotiation. Mobile Albania leaves the theatre to try out site-specific forms of assembly in urban and rural spaces. And the Zaungäste process the presentation form and organizational patterns of choirs.
