This performative sound exploration embraces the ecologies of rhizospheric territories. From the development of an open hardware biotransmitter we are interested in amplifying and sonorizing the electrical potentials that emerge from this symbiotic assembly between soils and bodies by hacking FM radio communication networks. This great hybrid organic radiophonic network weaves an exploration of the terrestrial-local and the remote-global as an exercise to imagine and generate new spaces and channels of interspecies communication and gestures. Listening to what the rhizosphere hides opens a door to new and possible interspecies gestures.
