His work is deeply rooted in scientific observation as a window that allows us to look through and beyond our own experience, to understand the complexities of things hidden from the naked eye. His work steps outside the human-centered worldview, exploring the threads that weave us into relationship with the more-than-human world.

David Abram, a cultural ecologist and geophilosopher, is the author of The Spell of the Sensuous and Becoming Animal: An Earthly Cosmology. Described as "revolutionary" by the Los Angeles Times, as “daring” and “truly original” by the journal Science, David's work engages the ecological depths of experience, exploring the ways in which sensory perception, language, and imagination inform the relation between the human animal and the animate earth. David was the first contemporary philosopher to advocate for a reappraisal of indigenous "animism" as a complexly nuanced and uniquely viable worldview – a complex reassessment now underway in many disciplines.

In his first book, David coined the phrase "the more-than-human world" in order to speak of nature as a realm that thoroughly includes humankind, yet also necessarily exceeds humankind; the phrase has now been taken up worldwide within the broad movement for ecological sanity. Dr. Abram has received numerous awards, including Rockefeller and Watson fellowships, and the international Lannan Literary Award for Nonfiction. Co-founder and Director of the Alliance for Wild Ethics (AWE), David has held the international Arne Naess Chair in Global Justice and the Environment at the University of Oslo and was recently the Senior Visiting Scholar in Ecology and Natural Philosophy at Harva University. He makes his home in the foothills of the southern Rockies.

Diana Obando (Bogotá, 1987) studied Political Science and Creative Writing at the Universidad Nacional de Colombia. She received the 2022 Elisa Mújica National Narrative Prize for her short story collection Erial (Laguna, 2023).

Modern Biology has brought 'plant music' to the masses. Originally educated as a biologist, veteran musician Tarun Nayar brings his passion for nature and sound together in an ambient project that is organismic, immediate, uplifting, and deeply contextual. He uses modular synthesis, home built synthesizers and other analog equipment to improvise with the natural vibrations of a certain place and time — via plant bioelectricity, latent electromagnetic radiation, and even the earth’s resonant hum. Trained from childhood in Indian classical music, he uses the system of Indian raga to mold his musical choices for time of day and season. His performances are an effort to bring the listener into the present moment through vibration, space, and connection.

His videos have been viewed over 100 million times and amassed him over 1 million followers online, and he has been featured by The Guardian, LA Times, BBC, Genius, Vice, The Verge, and DJ Mag among others. His recent albums have received editorial support on Spotify’s Music for Plants, Deep Listening, and Lava Lamp playlists. Recent live performances include Art Basel (Miami), MOCA (Los Angeles), New York Botanical Garden, and the Vancouver Art Gallery. 

Tarun is passionate about protecting wild places and has committed the lion's share of the proceeds of this project to supporting the natural world.
