How do we write and sound in a telluric way? Can we become stone and become voices merging with other stones? Can these ways of sounding establish relationships of resistance? ‘Petropolifonías telúricas’ is a poetic-sound performance by Soledad F. Rodríguez and Cristian A. Arancibia, emerging from various artistic practices within the framework of Soledad’s doctoral research, which explores alternative narratives of vocality through the figure of the nymph Echo—that being condemned to repeat the voices of others and who, in turn, was dismembered, her body transformed into stones. This performance works with companion stones as a means of establishing a poetic collaboration with them. Drawing on various incorporated sound-writing practices, influenced by Ursula Le Guin’s concept of terolinguistics, a sound-poetic performance is proposed in which voices are transformed into telluric stones — and vice versa — and words are broken and chewed, seeking other ways of speaking, sounding and listening in a petro-polyphony among diverse voices, languages and images. From these telluric compostist voices emerge clamours against the devouring capitalism that crushes them—voices-stones-bones seeking justice through the perpetuation of memory and against the prevailing andro-anthropocentric order that silences them—all within a sonic poetic cluster that offers a glimpse of the fissures in our world in ruins.
