cyberBanshee (aka Hannah Reardon-Smith) and digital media artist Amelia Hine have created 3 short and very strange music-films, exploring speculative underground existences. In keeping with our previous collaborative practice this three-video narrative collectively focuses on underrepresented nonhuman experience, in this case the largely hidden subterranean world of groundwater and stygofauna, infused with eerie electro-flute soundscapes. In creating a sense of momentum and tension through the works, we consider the impact of anthropogenic change on the largely invisible underground through abstract representations, and move toward a speculative future of sub-terra post-nonhuman, playing on the multiple definitions of posthumanism and extending them beyond anthropos exceptionalism.
