As a composer, Mathias Coppens himself provides the music, with an ambitious score that meditates on the formation of minerals. It is no coincidence that these are the building blocks of a planet that make existence possible. It is also no coincidence that Mathias links the idea of collective participation in the performance to the most important political and ideological question of the 21st century: how do we live together? How do we, as humanity, treat the earth, and what can this behaviour lead to?

Visually, I was responsible for an abstract translation of the score, with sinuous figurative motifs referring to geological processes. This aesthetic never becomes demonstrative, not even when the fog machine is brought out. On the contrary, with the artistic team we managed to create immersive worlds with minimal resources. It is the use of generative video and sparse lighting that makes the effect unparalleled.

Initially, I was supposed to join Benjamin on this journey but was unfortunately prevented from going. A month later, we undertook a trip along to the locations that impressed Benjamin the most. I recorded these through 3D scans, with those impressions I went to work and created various worlds that the tour depicts internally and externally. As a viewer, you step along, as it were, to the rippling music.

Through the James Webb Space Telescope – NASA’s most powerful telescope – the team discovered the presence of water vapour, sulphur dioxide and sand clouds on the exoplanet WASP-107b. Using specialised imaging techniques, Klaas Verpoest and Johan Van Looveren captured this almost indecipherable data (an endless stream of numbers) from a planet never really seen.
The results of this groundbreaking study were published by the leading scientific journal Nature on 15 November 2023. Immediately afterwards, the news found resonance in the national and international press (VRT news, De Standaard, De Morgen, HLN, The Guardian, USA Today, The Independent, Forbes…).

Imagine if we could analyse a recording of ‘Why Patterns?’ using the same mathematical algorithms employed to study exoplanets, and we were able to discover and analyse unique patterns. What if, based on these recurring patterns, we could attribute unique surface characteristics to the world of ‘Why Patterns?’, allowing us to shape this world and represent its evolution over time in an abstract visual narrative? What if this method also enabled us to interact with other so-called celestial bodies within the Feldman universe, such as the new compositions by Jean-Luc Fafchamps and David Fennessy?

Het Collectief – Chamber Music Quintet asked composers David Fennessy (IRL) and Jean-Luc Fafchamps (B), both of whom have a strong affinity with Feldman’s work, to compose new works for the same unique ensemble. I was asked to develop a visual counterpart for these three compositions.

In this project, Professor Leen Decin, an astrophysicist at the Institute of Astronomy at KU Leuven, and her team play a key role. Her research on exoplanets, which uses mathematical algorithms, offers an innovative approach to analyse the recording of Feldman’s ‘Why Patterns?’ in a similar way. By examining patterns in the music as one would with exoplanets, her contribution provides new insights that help shape the visual representation of the composition. This scientific perspective enriches the artistic interpretation, making the potential patterns in Feldman’s work visible to the audience.

The performance consists of the following works:
Why Patterns? (1978) Morton FELDMAN (1926-1987)
New work by (2026) David FENNESSY
For Morton Feldman (2025) Jean-Luc FAFCHAMPS
Why Patterns? (2026) Klaas VERPOEST

Holographic Duality presents an artistic tribute to the work of Juan Maldacena. Starting from the tiniest elements in sound and vision – particles and glitches – the work attempts to bridge the gap between string theory and a black hole. Sonic matter activates resonating objects, but also fills the dark place in the center of the sound world. Visual matter surprisingly reveals a vibrant hidden world through unexpected interactions. While both seemingly develop independently, they unavoidably collide in an audiovisual explosion. But is this the end, or only a new beginning? 

Visual artist Klaas Verpoest and musician Vincent Caers, both in a PhD trajectory and residents at BAC Art Lab, share an interest in the common ground between art and science. Through recent concerts and installations, created in close collaboration with physicists prof. Thomas Hertog and prof. Stéphane Detournay, they explored astrophysical phenomena such as black holes and the edge of space and time. 

Especially for this event, they created a short performance as a tribute to the honorary doctorate of Juan Maldacena.

Is there life elsewhere in the Universe? How do we detect exoplanets? How do we hope to find life on exoplanets light-years away? What is “TRAPPIST-1”? What do exoplanets tell us about the famous “Fermi’s Paradox”?

The Copernican Revolution taught us that our Earth, far from being the center of the Universe, is only one among the many planets orbiting the Sun, which is itself similar in every respect to the stars lining the celestial vault. Later, astronomy revealed that there are hundreds of billions of stars in the Milky Way, our galaxy, and that there are hundreds of billions of galaxies in our expanding Universe. Faced with such immensity, it is very tempting to hypothesize the existence of other inhabited planets out there, and even of other advanced civilizations. Long confined to speculations, the existence of exoplanets, i.e. planets in orbit around other stars than the Sun, became a proven fact at the end of last century. Since then, more than 4000 exoplanets have been detected at an ever-accelerating pace. A few dozens of these are “potentially habitable”, i.e. they could be rocky worlds harboring oceans of water on their surface, like our Earth. Imagining complex forms of life on some of these planets is but a small step away, one that is happily crossed by science-fiction. But our imagination will eventually be replaced by real scientific measurements, as upcoming giant telescopes will soon be able to probe the atmospheric compositions of some of these extrasolar worlds, and, who knows, to reveal chemical traces of life out there. If so, our view of the Cosmos will change forever…

‘The Solitary One’ is a performative installation transforming the most extreme and paradoxical object that our universe harbours – a black hole – into an immersive audiovisual experience.

Visual artist Klaas Verpoest, sound artist Vincent Caers and cellist-composer Benjamin Glorieux tend to unite art and science in their individual work. A shared fascination for the inexplicable aspects of a black hole and the concepts of space and time led to a joint venture in which they explore the artistic potential of their combined disciplines for illustrating these themes. Along the way they collaborated with theoretical physicist Stéphane Detournay. Their aim is not to provide a scientific explanation, which remains the scientist’s task, but instead to create an immersive installation offering the audience an opportunity for experiencing cosmological phenomena and the incredible forces driving them.

The End of Space and Time concert was the closing event of the Strings2019 conference at Flagey, cellist Benjamin Glorieux and I crafted a unique performance inspired by the concept of ‘strings’ in all their forms.

Eager to explore this theme to its fullest, we expanded the ensemble by inviting pianists Anthony Romaniuk and Rembrandt Frerichs with his trio—bringing the total to around 464 strings—and five fellow cellists, contributing another 24 strings. While electronica wizard Jo Thielemans didn’t bring any strings, his electronic sounds added an additional texture to the performance.

The result was as multifaceted as a diamond, with the timeless music of J.S. Bach serving as a subtle thread throughout. Yet, the sounds that emerged were entirely fresh, as if sprinkled with stardust from the nearly 500 strings, brought to life through the performers’ creativity and the otherworldly acoustics of Studio 4.
