THE EVASIVE CHOIR

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”.

Vernissage: Mar 5, 2021 – Apr 21, 2021 @ ICA Sofia

#BIOCOIN: Bulgarian Lev

2021 | Interactive sound installation

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

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, including works by Otto Dix, Hannah Höch, Joseph Beuys, Günther Uecker, Gerhard Richter, Antoni Rayzhekov and was funded by the DA LAB Foundation, Goethe Institute-Bulgarien and supported by Structura Gallery Sofia
Exhibition opening: 27 Oct 2020 - 9 Dec 2020 @ Structura gallery, Sofia / Bulgaria

#BIOCOIN (ORGANIC OSCILLATORS Series)

Music of bacteria colonies grown from money

2018 | interactive audiovisual installation and performance

#BIOCOIN is an interdisciplinary project exploring the sonic properties of bacteria found on money. #BIOCOIN is an audiovisual installation and a performative instrument that transforms, in real-time bacteria colonies in petri-dishes grown from coins and banknotes into music. The installation performs through a technique called sonification or auditory display— a process and a methodology of translating digital data into sound.

The project is created by Antoni Rayzhekov in collaboration with the micro-biologist Tanja Machuer (Robert Bosch Research Institute, Renningen, DE), Hagen Betzwieser - camera & photography, Lisa Przioda - Coordination (Robert Bosch GmbH), Sophie-Charlotte Thieroff - Coordination (Akademie Schloss Solitude) within the Art&Science and Business residency "PLATFORM12" - a fellowship program and an art residency by Akademie Schloss Solitude (Stuttgart,DE), Robert Bosch GmbH and Wimmelforshung (Berlin, DE) in 2018.

#BIOCOIN: Solo (ORGANIC OSCILLATORS Series)

for living bacteria found on money

2018 | interactive audiovisual installation and performance

#BIOCOIN:SOLO is an audiovisual installation and a performative instrument transforming, in real-time, living bacteria grown from coins and banknotes, into sound by using computer vision and sound synthesis. The installation performs through a technique called sonification or auditory display — a process and a methodology of translating digital data into sound.

The project is created by Antoni Rayzhekov in collaboration with the micro-biologist Tanja Machuer (Robert Bosch Research Institute, Renningen, DE) and Dimiter Ovtcharov - 3D modeling & sculpture production, Hagen Betzwieser - camera & photography, Lisa Przioda - Coordination (Robert Bosch GmbH), Sophie-Charlotte Thieroff - Coordination (Akademie Schloss Solitude) within the Art&Science and Business residency "PLATFORM12" - a fellowship program and an art residency by Akademie Schloss Solitude (Stuttgart, DE), Robert Bosch GmbH and Wimmelforshung (Berlin, DE) in 2018.

Tissues (ORGANIC OSCILLATORS Series)

for Heart, Brain, Lungs, Skin Cells and Modified Microscope

2018 | interactive audiovisual installation and performance

How do heart cells differ in sound compared to brain-cells or lung from skin cells?

The audio-visual installation - Organic Oscillators - created by Antoni Rayzhekov in collaboration with Dimiter Ovtcharov - 3D modeling & sculpture production, is attempting to reveal through sound the underlying relationships between cells and compare different tissues by sonifing the cellular structures and patterns. This is done with advanced microscopic imagery, computer-vision and sound-synthesis. The installation enables one to examine and sonify an image seen from a microscope in real-time.

feat. Katharina Koeller

2016 | Audiovisual Composition

SOMAPHONY is a project commissioned by Intel in 2016, resulted in an audiovisual composition that can be played as an instrument and is embodied in a physical object representing the interface to the composition itself. The interface is named - SOMAPHONE - a device integrating generative music and visualization technology in one combined audio-visual instrument. It uses biofeedback, such as heart-rate, Galvanic Skin Response, movement and gestures as a natural and expressive interaction between the composition and the performer. more...

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.
