Geophonography is a practice of sonifying the geological record, of tracing what Friedrich Kittler referred to as “signatures of the real.” The aesthetic efficacy of techniques for audifying and visualizing data derived from geological materials is discussed within the context of Ur-writings , a piece by the author first exhibited in 2013. Tracing a line through the work of Freud, Adorno, Kittler, Ballard and Derrida, geophonography is positioned within a cultural context that has continued to draw inspiration from speculations upon the relation between earth and mind.
