Coinciding with Documenta Fifteen

Location: Staatstheater Opera Foyer

Between Documenta Halle and Museum Fridericianum

Monday - Saturday

The work is available during opening hours

Until 24 September 2022

Participation: Visitors are invited to experience the artwork together in pairs. However, if you attend the exhibition by yourself, we recommend the set starting times: 13:00 | 15:00 | 17:00, so that you can experience the work with another visitor.

Duration: 16 min 23 seconds

Language: English

Medium: Sightless Goggles, Voice Instructions, Three-Dimensional Sound, Synchronized Movement, and Touch


To experience the artwork, you will collaborate with another visitor to perform different parts in a score, two different material qualities that impact each other: water and stone. Instructed to perform two vastly different material qualities, the two visitors depend on each other's perspectives to form a coherent reality. The fluidity and responsiveness of water are supported by the direction and ground of stone. Together, you will form the virtual space of a river. You will shift positions and roles.

As a participant in the work, you will be asked to augment your own reality by engaging with that which is not you, but of which you are a part, because in Symphony, without the other person, your sensory interface to the world would be incomplete.

At times you will be wearing goggles that induce a spatial white-out. The Sightless Goggles can be seen as a kind of proto-technology. They partly render our sensory interface to the world incomplete, and partly enable a new relationship with the surroundings by blurring the distinction between sensing/reasoning and body/mind. A guiding hand slowly earns our trust, while a whisper in the ear synchronizes your movement across the floor with the architectural sound in the headphones, closing the sensorial loop between your body and the imagined space through a reversed engineering of vision. Here, the value of agency and guidance is constantly negotiated in a dance of listening, adapting, and responding to the cues we learn to read with our bodies: to the immediate movement of your partner, as well as to a flow of past interpretations and tacit knowledge stored in the work's score, which surfaces in the close contact and friction between visual and auditory organs, the nerves and the skin of the two bodies temporarily becoming the artwork.

Adapting to the present context and locality of Temple of Alternative Histories and Documenta Fifteen, this iteration of Symphony of a Missing Room in Kassel emerged from an internal exercise: how to become a river. Shaping and being shaped by different topographies, the work echoes natural processes, in a practice of extending one's sensory experience into one’s surroundings.


You are the gravity pulling me downhill,

leading me to follow through the path of least resistance

Together we grind boulders, chisel away mountains,

and transport rocks and sediment downstream


Can an artwork learn?

And then,

- where would the memory

be retained?


In 2008, artist duo Lundahl & Seitl used a cast collection as their studio, wanting the sculptures to stare back at them. Their intuition was that reality is so immensely sensitive to its perceivers, it is ultimately shaped by them. This is the start of a process that builds on over a decade of phenomenological research in Museums, Biennales, and Art Centres from all around the world.

Throughout the years, Symphony started to incorporate the reverberation of its host's architectures into every next iteration of the work. By integrating these learnings into the work’s choreographic score, as triggers for future experience, we were not collecting individual sounds, ideas, or spaces from the past, but rather, enacting the past to play out horizontally in the relationship between two visitors' bodies in the present. A multitude of ideas and experiences, thoughts, and reflections echoes inside the symphony as an endless conversation between presences and absences. Making the learnings part of its body, Symphony gradually made itself independent from the institutions where it was conceived.

Each new iteration of the Symphony is made in resonance with a local place, and becomes an event in the history of an artwork that continuously projects into the future. The places and ideas that shaped its form until now, are carried forward in time and touch the present context at a distance, via the visitors' bodies. The artwork only exists as and when two visitors enact the score. When an iteration of Symphony has passed, its score is kept and maintained by the local site. Due to their ability to receive a world - the experience flowing through their bodies - the visitors are the artwork's true owner and the wetware repository of the artwork’s learning.

Garden of Ghost Flowers

Lundahl & Seitl and Untold Garden

7-10 April 2022


Garden of Ghost Flowers is a virtual being that feeds on the voices of those who visit it.

It is inspired in part by two things; firstly the sociological concept of resonance, defined by sociologist Hartmut Rosa as a mode of interacting with the world that is not based on control, but rather in an attitude of open listening through which one can be truly affected by the other. Secondly, it is inspired by Monotropa Uniflora, commonly known as the ghost flower, a plant that abandoned photosynthesis, survives in darkness, and feeds on the fungal web in the earth's soil.

The experience takes place in a biosphere that holds a digital life-form modelled after the traits of the ghost flower - an entity that feeds on human resonance: networks of human qualities, such as listening, caring, and adapting, expressed through the voices of the visitors. The life cycle of the Ghost Flower lasts for 20 minutes and can accommodate a group of up to 20 people, the vocal interactions of which form a unique biotope from which the digital flower grows. Some groups are deserts, some are lush forests, while others are something else entirely.

At first, the growing flower might be fragile and tender, but as soon as it gains strength from the collective resonance, it grows and thrives, subsuming the group until it blurs the boundaries of its constituents. Like with its biological counterpart, it is uncertain if the virtual Ghost Flower is symbiotic or parasitic. Where does the human end and the flower begin?

As the object to create resonance is the human voice, we invite you to the challenge of not using your voice for one hour before entering the biosphere.

Lundahl & Seitl, Monograph, Solo Exhibition, Norrtälje Art Gallery 17/10 - 29/11 2020

Lundahl & Seitl's works of art are philosophical investigations of boundaries and connections between the living, different objects, places and environments. The works have often been created as commissions on behalf of museums, art galleries or biennials from around the world and this is the first time we will see their works from different periods: from 2014 - 2020, simultaneously in one and the same exhibition.

The exhibition at Norrtälje Art Gallery is based on how their art relates to and is defined in relation to other artists' works, institutions and disciplines. From the start of their collaboration in 2005, Lundahl & Seitl have devoted themselves to the in-depth research of how perception acts as an active medium. Where and when do works of art exist?

Currently the duo is working on a new commission of the Symphony-piece for the Uppsala Art Museum, in which the artist and writer Peter Weiss plays a significant role. Through the concept of ekphrasis, the piece researches the seamless shift in position between physical and virtual museum spaces and art objects, as well as how this is mutually crafted by the imagination of the artist and beholder.-

Not Here Alone, Nor for Ourselves Alone


24th June 2020

This event is created in partnership with STUK, Uppsala Museum of Art, Centre Pompidou-Metz and Berlin Artlink.

Taking Lundahl & Seitl's new adaptation: AmissingRoom as a starting point, we invite you to an evening of reflection upon the lockdown period, to question the affordances of reciprocity and presence in times of physical distancing, and to consider how we can balance resilience and resistance when adapting to a changing environment.

You are invited to enter AmissingRoom, a score for two people 'being at hand', at 8 pm CET in front of your window.

Once you have experienced the app at home, we hope you will join us on zoom at 9 PM CET, where Lundahl & Seitl will be in conversation with Karen Verschooren, art curator at STUK (BE) co-commissioner of AmissingRoom for around 30 minutes. This followed by audience reflections and a 15 minute Q&A.

Setting the Stage - the background to AmissingRoom

In response to the coronavirus pandemic, digitalization and surveillance accelerated, laws were reconstituted and living habits altered around the world.

Yet, confronted with this rapid transformation, how can we ensure to keep alive what should only be temporarily altered? How can we protect that which: cannot (yet) be digitalized, risks becoming extinct, or will be forgotten if not practised or cared for in this present.

With lockdowns postponing or cancelling most cultural events for the rest of the year, we asked ourselves; could our work, Symphony of a Missing Room, which is dependent on its visitors, at least temporarily survive through adaptation outside the settings of a cultural institution?

In March 2020, Symphony therefore transmuted into an app: AmissingRoom: a score for two people to enact the artwork in a domestic setting.


The artwork Symphony of a Missing Room was conceived in and for the context of museums, with over a decade of research; a multitude of ideas, thoughts and reflections from over 20 international museums and biennales, virtually accumulated inside its body. It is reminiscent of how individuals from different generations live side by side, interact with each other, but somewhat fail to coincide and share each other’s realities. Inside the missing room, visitors pass through walls, into tunnels that travel through a network of past exhibitions and museums. Other artists, dead and alive, far and near, echo inside the symphony as an infinite conversation.


The artwork AmissingRoom places us in a liminal room, a speculative future where coming generations no longer share our present perceptual sensibilities to experience art. AmissingRoom is nothing that you look at on a screen, as with Visual AR artworks where a digital object appears superimposed in the room. Rather, it is a process between two people using their phones as makeshift VR headsets.

Led by the artwork's score, you close your eyes, and the voice in your headphones synchronizes your movement in space with a sound architecture, carried by the unseen hands of your friend. The artwork is thus the phenomena that emerge. More than the sum of its parts, it is a reciprocal space with dimensions measured and received by the participants' imaginations.

Words fail those experiences existing beyond descriptive language. And in the face of this, Lundahl and Seitl have spun their poetry into syncopated verse, a counterpoint between the unknowable and the unsayable. They have paired Agnoseology with the Unsayable, immersing you within an experience as majestic, as it is disquieting, just there, . . . . right there, . . . . . yet, forever adrift from language.
