Do trees dream of CO2? with Per Hüttner
Immersive experience in dialogue with a tree
Per Hüttner is an artist who has been working for years on live performances that translate our brain activity into sound via electrodes. One of the estate's trees has been fitted with a Pépipiaf (an ecophysiological measurement tool) that reproduces in real time the changes in its diameter as a function of the season, temperature, time of day and humidity. Carpets arranged in petals around it, above its roots, will allow us to lie down in contact with it. Karine Bonneval will be recording the activity of the soil near the roots, and Per Hüttner will be supervising them live with data from the tree, in quadraphonic sound. Taking the time to listen together to these sounds, those of other living beings around us. One person is fitted with an EEG, and his or her brain waves, transformed into sound, vibrate a speaker directed at the roots of the tree. We listen to the delicate, subtle sounds, and let the tree hear the brain activity modulated directly by these sounds.
