Sites of infection investigates how power acts on bodies (including interspecies forms) via social processes of replication, amplification and echo. How do sonic traces of late era capitalism effect organic forms and how much of the production of capital is a vibrational bodily pollution – in particular those low in the food chain of capital value? What is the ‘playlist’ of economic extraction and what do the vibrations of capitalism’s wavelengths do to our biological states? The work develops a visual exchange (a co-operative dialogue) between data noise/verbal abuse and algae. Algae is chosen for its relation to the artists bodily regimes of consumption and also as an indicator of climate health. The work submits jars of oxygenated algae strains to data noise and internet hate speech to measure visual and growth response. At a fundamental level I want to consider how texts (the written/spoken and vibrating social outputs of our culture) affect relational and embodied knowledge.
