Printemps Silencieux


Printemps Silencieux (Silent Spring) takes us to the year 2162 in the city of Enapolis, where the inhabitants are walled in and have never known or even felt the presence of the ‘outside’. Upon entering a room of the city museum, the visitor can read the following label:

‘The Enapolis Museum regularly excavates our basements. We find a number of objects, mostly damaged, obsolete or unknown. Among them, a device that could finally be restored and explored. It appears to have belonged to Gaëtan Gromer, a 21st-century sound artist who lived on the Enapolis construction site. It is likely that, throughout his life, the artist collected a considerable database of field recordings recorded by himself or by collaborators. According to what we have discovered about this device, the practice of field recording consisted in particular of recording, in the open air, sounds produced by human activities and/or by the natural environment.

This exceptional document from the beginning of the 21st century allows us to give you the opportunity to listen to these astonishing ‘soundscapes’ composed of typical sounds of the environment of this distant time and which have probably all disappeared in 2162.

The title was inspired by an unfinished work by the artist referring to a prophetic text written in 1962, exactly two centuries ago, by an author named Rachel Carson.

A tree appears to be covered in concrete. A deep, gravelly sound is emitted every time the world’s forests permanently lose, due to massive deforestation and the relentless artificialisation of the world, the equivalent of the total area of the city block* you are currently in. This process makes it possible to give substance to this staggering statistic: currently, one hectare of forest disappears from the surface of the globe every 1.11 seconds. 

But from this sinister tree springs a small branch from a small living shrub: a strawberry tree (arbutus unedo). A pyrophilous plant, the dormancy of the seeds of the arbutus is lifted by contact with fire, allowing it to conquer areas devastated by fire.

Sans faire de vagues …

Sharks are massively affected by the lucrative finning trade. Since the 10th century, a number of miraculous virtues have been attributed to them. However, it has been widely demonstrated that this is a myth and that, on the contrary, they are bioaccumulators and therefore carriers of high concentrations of heavy metals. Ironically, they have no taste.

The work consists of three life-size shark sculptures (white, hammerhead and thresher) with their fins removed. Every time it makes a sound, somewhere in the world, a shark is thrown back into the sea, mutilated, doomed to several days of agony. The finning trade is so huge that the overall shark population has declined by more than 90% in exploited areas. The disappearance of the largest predator in our oceans would, however, cause major imbalances in the marine ecosystems that provide most of our oxygen. 

Gaëtan Gromer, in an artistic approach that questions the use we make of figures today, brings us face to face with an unknown reality. Using the astonishing power of suggestion of sound, coupled here with a visual representation that leaves no room for misinterpretation, the artist questions this very strange fish market.

Enapolis is a piece of work that reports the artist’s critical and worried look at the current evolution of urbanism in the face of climate catastrophes. It is inspired by ‘building worlds’, in which it would be possible to spend an entire life, from the maternity ward to the mortuary, without ever leaving.

The project in brief: 

Enapolis was inspired by the work of geonomist François Terrasson. In the 1980s he sought to answer the question: ‘Why does technological man destroy nature?’ ». His research, supported by dozens of collective experiences, led him to formulate a simple and clear answer to this question: ‘because he fears the wilderness’, a deep and largely unconscious fear. Man therefore logically protects himself from his fear by destroying its source. In Enapolis, we can literally measure the phenomenon. On the floor, the square of light highlights a concrete surface. The music (on headphones) is created from the sounds of jackhammers. With each sound impact, the equivalent of this area is artificially damaged in the world.

At the heart of the installation, two sculptures explore another way of protecting oneself from nature. They are inspired by recent ‘world building’ projects, in which it would be possible to spend a whole life, from the maternity ward to the mortuary, without ever leaving. For the designers, it is a question of perfectly controlling the environment of the inhabitants and envisaging a possible response today to the possible disaster that is coming. The irony of our species is that our fear leads us to make nature more and more threatening and thus to increase our impact and its potential consequences. A feedback loop that could generate others…

In the darkness, LEDs flash.

An immersive sound environment lets you hear glaciers cracking and icebergs melting.

Can sound say something about the changing world?

The project in brief:

Scintillements is a sound journey to the heart of glaciers composed from recordings made by the artist at Jökulsarlòn at the foot of the Vatnajökull in Iceland and on various alpine glaciers (Glaciers of Glaciers, Tour and Girose).

The installation, which is also illuminated, causes a flash to appear each time the world’s glaciers permanently lose a volume of ice equivalent to the overall volume of the place in which the work is exhibited. 

The sound composition consists of the thuds produced when the seracs fall, the heavy cracking of the friction between the ice mass and the earth due to the movement of the glaciers, and the fizzing of the air bubbles released into the air under the water as the ice melts.

For this work, Gaëtan Gromer, whose most recent works make use of sonification* (Lorette, Enapolis), uses light this time to evoke the 23.45 million litres that glaciers lose every second.

Yells-Atreuma is a speculative prefiguration of man’s remediation of his environment, enabled by the physarum polycephalum (commonly called blob) as a medium of communication and connection.

The project in brief:

Yells-Atreuma is a set of sculptures combining a software entity (neural network), a biological entity (physarum) and a synthetic entity (3D prints). Each module represents a vital organ (heart, lung, kidney, spleen, etc.) brought into contact with a living organism, the physarum polycephalum, which will colonise its host. The very title of the work: ‘Yells-Atreuma’ is derived from a textual generative program. It is one of many poetic and lexical possibilities produced by a neural network whose essential ‘feeds’ consist of two distinct lists. One lists all known pathologies in the world, the other lists several mythological, sacred and occult figures. From these specific and intertwined lexicons, a new form of language is produced, activated, shaped by the physarum and its movements on the organs. The latter then produces a meta-language, stammering and, paradoxically, sometimes complex, evocative, opening onto hybrid imaginaries. Yells-Atreuma is part of the ‘Mycore’ cycle, which proposes a remediation of the human being via a transformation by the fungi kingdom.

Photophonia is an installation inspired by an invention by Alexander Graham Bell (1880) using light as a sound transmission channel. Rid of the decorum and the discourse on innovation, Photophonia leads back to a raw and crude idea of technology, which can be seized and transformed into a poetic and political gesture. 

The project in brief:

The installation uses the movement of two flashing lights as sound transmitters. The circular movement of the mirrors around the bulbs produces a hypnotic sound vibration. The reception, made possible by small solar panels connected to an amplifier, produces a noisy, raw and yet fascinating result. This protocol offers a potential of construction and propagation of small networks whose manufacture is accessible to everyone. The question of the codification of information underlies this creation, notably by articulating the politics of data and the plasticity of light, its universality and its ephemeral beauty…

The project in brief:

A contemporary reinterpretation of the war memorial, Lorette is a set of sculptures including eleven authentic shell casings from the First World War set in resonance by a system of firing pins. Throughout the exhibition, from 4 October to 23 December 2018, the installation played 18.6 million notes, one for each death in the conflict. Through this process of data sonification, Lorette gives body to mortality data, repeated so many times as to become abstract; so enormous that they exceed our faculties of immediate representations. As a tribute to those who lost their lives, the stele highlights their words through the lyrics of the famous Chanson de Lorette, written and sung by the “poilus” (French World War soldier) since 1915.

Composite relational sculpture from which vibrated sounds emanate. ORGAN is an audio-tactile installation that invites the public to place themselves ‘in’, to snuggle ‘against’, to embrace, to move objects from which vibrating music emanates. Sometimes active, sometimes passive, the spectator places themselves between, on and under the objects and becomes part of this sensitive matter.

The project in brief:

ORGAN is a composite organic relief from which vibrating sounds emanate. ‘The closer I get to it, the more I’m part of this landscape. Or is it more of a part of me?’

ORGAN is an invitation to a playful, contemplative or even meditative journey. Far from supersonic speeds and internet flows, ORGAN is a work of slowness, of the tiny and the close.

This interactive sculpture brings into play not only the sight and hearing of the spectators, but also their touch through physical interaction. The skin is the main transmission interface, the membrane through which this disconcerting experience of sound and vibration passes for those who take the time to try it. It is an intimate and gentle experience made up of recesses and reliefs.

Hidden inside each object, a discrete audio-vibrating technical device diffuses sounds and vibrations through a network of speakers and vibrating motors. Each object has a sound and vibro-tactile identity, each one has its voice, its moods, its personality and together they create a spatialised polyphony both sound and tactile.

This project is a continuation of the research on audio-tactile works conducted by the artist Lynn Pook since 2003.

The project in brief:

Evaporation Silencieuse, by Nicolas Schneider, is a collaborative work evoking the imbalance of our landscape. It is concretely composed of a set of drawings made with ink and watercolour by the artist, in a sedentary, virtual and mental journey, thanks to the use of digital tools. In addition to the visual installation, a sound composition by Gaëtan Gromer enhances the spectator’s experience. Using field recording, the practice of composing music from field recordings, the sound artist equipped himself with hydrophonic microphones and walked the same routes.
