Between This and That is It

old typewriter augmented with AI

2023 | Interactive installation

Antoni Rayzhekov & Martin Murer

modified 80s electronic typewriter, augmented with AI

“Between This and That is It” is an interactive artwork which augments an old typewriter with an AI, blending several decades of computerized optimization of text production. The artwork employs an offline processing machine learning-based language model embedded in a typical office typewriter from the 1980s. Deliberately diverting from the pervasive conversational user interface, the interaction style is based on a well-defined minimalist pattern of complementing two user-supplied words with a third word that – in the model – lies in the middle of the other two. This constraint interaction invites to explore the limits of the semantic space of language models and poses questions related to the topology of meaning, with respect to truthfulness, biases, and cliches, by creating a semi-intelligent poetic co-performance involving the audience.

This project seeks to foster a discussion on the creative collaboration between humans and AI within the constraints of machine learning technologies embedded into objects from the near past.

The advances in artificial intelligence and particularly the exponential development of language models have enabled a new generation of artistic research and production in the realm of New Media, Interactive Art, AI, and HCI. Language Models use multidimensional semantic vector spaces created by capturing the meaning and the context of the (textual) input into a series of numerical vectors called embeddings. Those embeddings are positioned in a multidimensional space in respect to their semantics, interrelationships, and context. Language models rely on vast amounts of textual training data obtained mainly from the web. Therefore, they naturally inherit all built-in biases, stereotypes and ideological beliefs.

The experience and the perception of the interaction are shaped by a hybrid space shared between the audience members and the AI, the mechanical limitations of the typewriter, the embedded mini-computer’s computational capacity, and the language model itself.

Drawing Exercises

for two performers and a bio-sensing drawing machine

2023 | Interactive installation

part of DIGI-Sense project; A. Rayzhekov, C. Schnugg, D. Brill & M. Jahn

two biofeedback and movement wearables, custom drawing software, projection

"Drawing Exercises" is a participatory performance piece by Antoni Rayzhekov for the DIGI-Sense project, a performative installation in which the audience become the performers. A series of drawings are performed by two participants together, who have to find out the movements, velocities, and strategies to carry them out.

The project aims to artistically explore different senses (visual information) and bodily movement for sensemaking with digital technologies. The participants in the "Drawing Exercises" installation wear custom-made sensor sets on their bodies, which are placed on their chest: a movement sensor, a heart rate sensor, and a stress sensor. In the first three tasks, the participants need to learn to collaborate through their movements to make sense of the interaction process between the sensors and the drawings they create through their movement shown in the projection. In the fourth task, the stress level starts to influence the drawing as a first challenge. In the final task, the heart rate sensor influences the drawing process, which challenges the two participants to integrate a new factor that cannot be controlled actively into their embodied drawing process, namely their haeart beats control the drawing process only when occuring at the same time. As sensemaking is also understood as a social process, the duos of participants in the interactive installation "Drawing Exercises" have to learn to collaborate with their movements to fulfill the following five tasks: draw a horizontal line, draw a vertical line, draw a circle, draw a landscape, draw a house.

The Distance Between Us is Music

participatory sound installation

2023 | Interactive 8-channel sound installation

part of DIGI-Sense project

surveillance camera, custom computer vision & sound generating software, monitor

"The Distance Between Us is Music" is a participatory octophonic sound installation, employing custom created computer vision and generative music systems. The interactive artwork explores the group dynamics of listening, interdependence and sense-making through sound and interactivity by using surveillance camera and real-time people detection algorithm which is generating music based on the distances between the audience members. The performative installation invites the audience who instantaneously become performers to move together, change the distances between them while exploring the emerging group dynamics and the available space in different rhythms. It is an act of listening and moving as part of sensemaking of space - physical and relational space - and creating sounds.

At the entrance to The Distance Between Us Is Music a monitor makes the movements of individuals in the space of the installation visible. It shows individual tracks, and the distance between the performers active in the installation. When performers leave the installation, their tracks only fade slowly, which adds an important temporal dimension. A single performer in the installation is never alone, as digitally the artist is always present as a partner to interact with. As the performers in the installation should focus on the sensemaking of the sound, space, and interaction with others, the visual representation is not intended as a guide for performers to understand their impact on the sound. It rather is a visual clue of what is and has been happening in the installation before they enter the space, a clue that is intended to make sense after the experience.

The project embodies a form of sonification of audience’s behavior and sense-making process, creating an unique experience where the borders between listener-audience and performer-author are entirely blurred. By creating such an active environment of sonic creation and feedback-loop between artwork and audience we situate the actual sense-making process as primal material of the artwork.

2023 | water-driven sound installation

UNTIL THE LAST DROP Series

old air conditioner external body, guitar amplifier, electronics, IV system, metal bucket, water

According to Charles Darwin evolution is fostered by adaptation. Today we are born in a world so adapted to our needs. The machines are but a part of our nature. The seasons are controlled by a remote. While pressing the buttons are we striving on our way of a new adaptation?

We owe our existence to water. Without it there will be no life, no people, no oceans, no oxygen. At the same time, water is a resource we daily exhaust, pollute, contaminate, with almost no repercussions.

Water is also an information network, carrying the code of natural renewal, the memory of millions of years and of every little life that has passed through this world. Water is life.

The installation is hooked on IV systems which is carefully refilled each day by the gallery employees. What will happen when there is no-one to refill the system?

sound installation by Antony Raizhekov in collaboration with: Bilyana Vucheva (violin), Rosen Zahariev (flugelhorn), Mathias Lebusche (piano); curator Ralitsa Gerasimova

Drop by drop…..the last drops of sustenance are running out. Exploitation knows no boundaries, knows no humility. While the last drops are flowing we are in the illusion of possession, but who knows how many are left?

The last drops of our humility are dripping. The last gulps of our very existence trickle down our already warped, twisted selves. Not much left, isn't it still dripping... This exhibition is dedicated to the last drops. Of those slow trickles that hint at the end, but trap us in the hope worn by the rest. Drip by drip...hear the drops, see the drops. Listen to their profile, touch them. These are the last straws.

Antoni Raizhekov's exhibition "Until the Last Drop" includes sculptural installations using flowing water that allows the viewer to experience the water drops, both as a physical object and sound form in the gloomy atmosphere of a dystopian temple, where the last drops sing their swan song.

ARTIKULAT

for biofeedback-articulated bass-flute, contra bass clarinet, piano, viola and audience under surveillance

2022| interactive sound-performance feat. NAMES

A work commissioned by the NAMES Ensemble (New Art and Music Ensemble Salzburg) composed by Antoni Rayzhekov in collaboration with Marina Iglesias - body-bass flute, Anna Lindenbaum - body-viola, Marco Sala - body-contra bass clarinet and Matthias Leboucher - body-piano

ARTIKULAT is a complex, participatory sound performance-installation for four musicians, an audience under surveillance and an audio-visual computer system including biofeedback, sound and visual synthesis and surveillance camera. Each musician is equipped with a special wearable biofeedback device – monitoring the body’s bio-signals during the performance, such as: heart rate, stress level and body movement. Each musician’s bio-signals are projected on the stage in real-time and are modulating short audiovisual recordings constructing the piece.

The work extends beyond the traditional musical performance, focusing solely on the articulation of the sound by the bio-signals of the performers, exposing something very personal and corporal, which usually remains hidden from the audience. By completely removing the material presence of the musical instruments on the stage during the performance we can focus on the detailed articulation of the physical and sonic experience of the performers. However, the computer system includes a surveillance camera, that detects every movement of the audience which directly affects the performance’s sound. The game of performing-while- listening now is shared between the performers and the audience and the group dynamics of the audience together with the bio-signals of the four musicians drives the resulting sound piece by creating a feedback loop between audience and performers. That “performing while listening” between audience and ensemble, as a feedback loop of social interaction, is explored in this work.

Fragile Perspectives

2022- 2021 | 5-channel sound installation

glass, metal, 5 speakers, electronics, A.I., news data, sonification

What do news landscapes look like and sound? And how can we transform them into tangible objects to see clusters of over-reporting or hear missing voices in under-reported topics? Based on the very large news information set, new glass tangible objects of news landscapes were produced by clustering 10000s of individual news articles into 300 dimensions, then reducing these dimensions to 3D maps. These 3D maps were then manufactured as glass objects and digitally scanned to excite virtual strings to produce the sound using a data sonification method based on physical modelling sound synthesis.

Nominated and exhibited at the "Global Digital Arts prize" exhibition in Singapore, organised by the NTU Institute of Science and Technology for Humanity (NISTH) and NTU School of Art, Design and Media (ADM), finalist at the Falling Walls in category "Art&Science". The artwork was presented at IRCAM // Center Pompidou during MediaFutures's DemoDays, as well as it was selected and presented at the art exhibition of C&CC 2022 in Venice and was part of the group exhibition “HOW SOON IS NOW?” in Structura Gallery, Sofia wth curators Maria Vassileva and Walter Seidl

THE EVASIVE CHOIR - REMIXED, 2022

2022 | sound installation

record player, 30 vinyls, 30 processed bulgarian politicians' interviews

THE EVASIVE CHOIR - REMIXED (2022) is a sound installation that deals with the topic of what was kept silent and unsaid in the public space by Bulgarian politicians during the period 1989 - 2021. 30 found interviews and statements from emblematic political figures in Bulgaria were used and were digitally processedso that the words are removed and only the unspoken, inarticulate sounds of discomfort and uncertainty, as well as an audible articulation suggestive of silence, are left. These sonic remnants are digitally processed by being both "stretched" to create an overall chorus-like sound, as well as rhythmically organized. The work builds on the multi-channel sound installation "THE EVASIVE CHOIR" from 2021.

The sound installation was part of the group show "Self-splaining (a Triumph of Empathy)" - orgabized by ICA-Sofa at the University of Pristina's Faculty of Arts Gallery as part of MANIFESTA 14 in Pristina, Kosovo, as well as the artwork was selected and presented at the 25th Gabrovo Biennial, Bulgaria and One Night Stand Gallery in Sofia.

The artwork is in edition of 3 installations and 30 vinyls.

THE EVASIVE CHOIR

ПРЕМЪЛЧИТЕЛИ (original title)

2021 | 30-channel sound installation

30 found interviews of Bulgarian politicans, 30 tin-cans, 30 speakers, 30 modified note-stands, electronics; variable dimensions

The sound installation “The Evasive Choir” creates a kind of “a chorus of the muffled”, which covers an important period in the recent past of Bulgaria. 30 open tincans contain speakers that reproduce processed interviews of key figures from the political and public life in Bulgaria since 1989. The interviews were digitally processed, removing the spoken words and leaving only the exclamations, the sighs, the inarticulate sounds of discomfort or those suggesting silence. All voices sound at the same time, keeping the length of the conversation - with the interlocutor, with each other, and with the audience in the exhibition

The work simultaneously archives and exposes the process of passing over in silence thus setting it as one of the possible reasons for the condition of society, as well as a metaphor for the inherited silence, atrophied public media and the difficulty of democratic processes happening without overcoming such a specific kind of “national silence”.

ORGANIC OSCILLATORS Series

8 glass petri-dishes, coins of 0.5 lev and 1lev, banknotes of 2, 5, 10, 20, 50 and 100 lev, epoxy, stainless steel, aluminium frame, built-in all-in-one computer, stereo speakers, amplifier, microcontroller, 8 potentiometers, custom software; dimensions: 120х60х11cm

In 2021 the project was awarded with a stipendium by the Bulgarian National Cultural Fund (NCF) within the program “Creative Initiatives” and the creation of the interactive sound installation #BIOCOIN begun by using bulgarian coins and banknotes in collaboration with mag. biologist Ava Cherkez and eng. Petia Logar from the team of DIACHIM Sofia.

The project #BIOCOIN examines critically the notion of value, transferring it into the realm of the biological and then the sonic domains in order to suggest a different perspective towards the distribution and the circulation of money. In doing so, it proposes an alternative notion of a “sonic” value.

PANDEMIC SOUND MAP

Music from pandemic statistics

2020 | interactive sound installation

COVID19 statistical data, steel, aluminium frame, 186 circuit breakers, electronics, speakers, custom software; dimensions: 200x100x10cm

The interactive sound installation “PANDEMIC SOUND MAP” transforms the statistical data on the spread of the SARS COVID-19 virus into sound, by means of sonication process based on the number of infected per day per country. On a metal political map of the world, 186 switches are located in the center of each country. The installation allows any number of countries to be "switched on" or "switched off" interactively in one common sound picture. This sound representation provides a new perspective on the pandemic, with the expressive means of sound art and digital technologies, reflecting the different approaches to controlling the pandemic, its scale, distribution and current state. The installation is an artistic metaphor for the impact of the pandemic crisis in political, social and cultural aspects, which, as a circuit breaker, almost "switched off" the world economy.

The project was part of the group exhibition "ART AND POLITICS - CONFRONTATIONS AND COEXISTENCE" curated by Maria Vassileva at the Structura gallery, including works by Otto Dix, Hannah Höch, Joseph Beuys, Günther Uecker, Gerhard Richter, Antoni Rayzhekov. "Pandemic sound map" was funded by the DA LAB Foundation, Goethe Institute-Bulgarien and supported by Structura Gallery, Sofia

BOREOUT

inspired by Marcel Duchamp's interview for BBC [1968]

2019-2018 | Interactive A/V installation driven by boredom

3-channel 4x2m projection, glass, EEG headset, electronics, custom software, stereo speakers, chair, lamp

BOREOUT is an interactive 3-channel audiovisual installation that is controlled by the visitors' tendency towards boredom or attention. The installation uses a mobile EEG brain-computer interface connected to an electronic system that analyzes brain waves in real-time and is assisted by artificial intelligence algorythms. If the visitor wearing the brain sensor is bored enough, the image and sound become recognizable and assembled in their original form, or, respectively, "blurred" when interest is detected by the system driving the installation. As a result, the image and sound oscillate between a "focused" and an "unfocused" state, leaving the visitor in a very peculiar state of "readiness" and "expectation".

The project was initially supported by Akademie Schloss Solitude (Stuttgart), Robert Bosch GmbH (Reninngen) and Wimmelforschung (Berlin) in 2018, and developed further at FERAL Labs Artist-In-Residence 2019 in Salzburg and Hallein - Austria during Schmiede 2019. Selected and supported by DigitalSpring 2020 Salzburg, Austria within the exhibition "STAND BY" at 5020 Gallery (canceled due COVID19)

2018 | interactive audiovisual installation and performance

ORGANIC OSCILLATORS Series

How do heart cells differ in sound compared to brain-cells or lung from skin cells? Organic Oscillators explores novel sonification techniques to examine the cellular structures and patterns as sonic scores, revealing the underlying relationships through sound. This is done with advanced microscopic imagery and computer-vision. A specialized software was created for the project, which enables one to examine and sonify an image seen from a microscope in real-time. Different specimens of cells were investigated and their sound qualities were compared. A range of different organic structures were similarly examined through several sonification techniques using image analysis, which included motion tracking, topological scanning and curvature unfolding.

TOPOLOGY OF THE SONIC BODY

Duet for body and scanner feat. Federica Dauri

2017 | Audiovisual performance-installation

2016 | Video-installation

"Topology of the sonic body" is an audio-visual body-installation performance, investigating the sonic properties of the performing body and its curvature in space through sound. A custom-designed audio- visual synthesizer is decoding the metamorphosis of the body- artist and performer Federica Dauri, translating in real-time, the body curvature into a stunning sound and light performance-installation.

“The body can be perceived as a complex living surface, consisting of multiple curves, manifesting itself through shape and topology. In that sense, it is a map, which forms a musical score – based on the body curvature, its shape, its expressive tensity and physical structure being the primary and only source of the sonic material. A specially designed machine is scanning the body and translating its curvature directly into sound. There are no prerecorded sounds or any other external sonic materials, than the body curve itself, extracted by a white line scanning the performer's body in real-time, during the entire piece.”

THESECRETCORNER.NET

after Johannes Cladder's The Secrect Corner (1984)

2017 | net-art

The original art project The Secret Corner by Johannes Cladders (1924–2009), the first jury chairman of Akademie Schloss Solitude was created between 1987–1993 and was installed at the French Académie de Muséologie Evocatoire and has been part of Akademie Schloss Solitude's archive since 2016. A box with 9 slides and 3 drawers was hidden in Warelwast (France), behind a special door equipped with an electric-mechanical system controlled by the direction of the wind. The box contains different every-day objects, trophies, drawings, as well as nits own descriptions and plans, carefully organized by Johannes Cladders with many references to artists from the Fluxus movement.

In 2016 Antoni Rayzhekov in cooperation with Jean-Baptiste Joly, Hagen Betzwieser (Camera Interviews) followed an idea by Jacques Caumont to transform Cladders's The Secret Corner in a online format. When the winds are favorable, the hidden part of the website becomes available and one can explore the secret corner and its contents, as well as insightful interviews with Jacques Caumont, about the work.

The project is commissioned by Jacques Caumont and created by Jean-Baptiste Joly - mentor, text, interviewer; Antoni Rayzhekov - photography, interactive stop-motion photo-animation, programming,software, hardware, web-design; Hagen Betzwieser (film and editing), Angela Butterstein (PR), Anita Carey-Yard (archive), Horst Kaag (technic), Françoise Le Penven (guardian angel), Katherine Vanovitch (translation), Kimberly Bradley (translation); In collaboration with: Martin Cladders, Wilhelma Cladders, Jennifer Gough-Cooper; in Normandy: Technical Support: Roland Tiercelin

Quantum Picture I

2012 | Participatory Audiovisual Installation

Quantum Picture series is a performative audio-visual installation sensitive to movement. An image is being constantly processed based on the viewer's movement by using computer vision and image analysis. The process is irreversible, the original is lost and one can see only fragments of the initial image and sounds remained from the last visitor. The quantum state of the installation is being altered in the process of observation. The project is inspired by the principals of quantum mechanics and quantum measurement.
