Vertimus

From november 11th to 15th 2019 Experimental Gallery, Tadjen Hall / Ag Quad, Cornell University, NY, USA
Vertimus

This exhibition presents the results of research carried out over three weeks of residency at the soil and crop sciences department of Cornell, at the invitation of Johannes Lehmann and in association with the "Sounds of Soil - tracking soil health for targeted pest control" research grant from Kyle Wickings ( CALS / Geneva Entomology), Johannes Lehmann (CALS / SIPS - Soil and Crop Sciences Section), Holger Klinck (CALS / Laboratory of Ornithology), Greg McLaskey (EN / Civil & Environmental Engr DEPT).

- Oak trunk, 2019: Two printed curtains of a microscopic view from an oak’s bark.

- Vertimus, 2019, is a film developed in collaboration with Eric Badel, from the PIAF, tree ecophysiology laboratory in Clermont Ferrand, France and Emilie Pouzet, performer. In a sphere illuminated at 360 degrees, a poplar tree that has been laid down straightens up thanks to its perception of gravity - gravitoception - without involving photoperception - perception of light -. This frame-by-frame sequence serves as a support for the performer to try to reproduce this righting movement with her (human) body. But exercise is not so easy, and it puts pressure on internal organs and unusual muscles. It is a way for a time to put oneself in the place of the plant, in its anchoring to the ground and its temporality.

- Sonic Rhizotron is a piece done during the residency. It is an attempt to see if root systems of plants (sunflowers and beans) and fungi are attracted or repelled by 5 sounds played in 5 pods. Low frequency natural sounds: Antarctic soundscape / Barred Owls / Sandai wave sound; Stefano Mancuso, plant “neurobiologist”, Firenze University, Italy says that this frequencies are improving the growth of plants; and sounds of potential predators of roots : grub / caterpillar eating a leaf.
- See the sound of soil, piece done during the residency. This image is the sound of a recording done Wednesday November 6 on soil near Bradfield Hall. The sound was recorded with an accelerometer and put into an image trough Raven, the sound software from the Lab of O. This sound can be heard in one of the 3 papier-maché /soil / herbs sounded sculptures installed outdoor in the Ag Quad.

- 50 shades of soil, piece done during the residency. 50 samples of US soil, from the project developed actually in the Soil and Crop Sciences Section: the National Soil Project. Each object is done from a specific soil, and the data are an extract of what you can learn from this samples.

- Outdoor installation, at the AG Quad: listen to the soil. Echoing the ongoing scientific research grant and inspired by this work, 3 new sound sculptures in papier maché and earth give the impression of 3 new soil samples recorded at Cornell in November.

The exhibition would not have been possible without the precious help of: Johannes Lehmann, KAR and Shiyi Li, Laurel Lynch, Itamar Shabtai, Rachelle Lacroix, Greg MacLaskey, Laurel Braden Symes, Holger Klinck, Louise Roberts, Craig Cramer, Taryn L. Bauerle, Kathleen C. Howard, Kirsten S. M. Kurtz, Verity Platt, Cindy Twardokus, Aimee Lehmann.
