Who is being empowered? Whose voice is amplified? Who is being made visible? For 15 years Anthony Luvera has worked with homeless people across the UK. Through long-term collaborative projects he explores the tension between authorship (or artistic control) and participation, and the ethics involved in representing other people’s lives. ‘Who Empowers Whom?’ considers the production of Assembly, created in Brighton between 2013 and 2014, to explore questions and tensions involved in unpacking the (im)possibility of a participatory practice to put power in the hands of the powerless.
