Age ten, I became trapped in the Community Charge demonstrations in Trafalgar Square, more commonly known as the Poll Tax Riots. Capteur (2019-2020) is a multi-form expanded essayistic work that recounts my personal passage and memories of the conflict, violence, and trauma, plus the political context of the Poll Tax Riot on March 31st, 1990. Capteur is a series of inter-related essayistic works, including theoretical texts, factual autobiographical texts and fictionalised texts written under a series of textual writing constraints, maps, images, models, collages, moving images, algorithms and coded works, sound works, audio recordings, performative collages and gestures. On the 29th anniversary I re-walked the route of the demonstration.
