(NON)OBSOLETE MEDIA is a six-month project in which phonon~ has joined forces with the Ústí nad Labem city Archive, where, among other items, an extensive collection of shellac gramophone records is hidden. The project is structured in several layers: digitization of analogue media, music composition, live performances and theoretical lectures. Artists from the Czech and German art scene are invited to participate in the project. Both internationally established artists as well as locally active ones, namely in Ústí nad Labem and Dresden.

Three events – on 30.11, 6.12 and 13.12 – are the public output of the project. During the events there will be presented original compositions created on the basis of archived and digitized sound recordings. They will present their work in the format of live playing and acousmatic compositions in quadraphonic sound: Marie Čtveráčková, Jan Macháček, Iñaki Rocha Echevarria, Jan Krombholz, Moisés Horta Valenzuela, Jan Burian, Vojtěch Groot, Antje Meichsner, Oliver Torr and Polina Khatsenka.

Audio performances are accompanied by talks & presentations: a presentation of highlights from the collection’s original owner PhDr. Vladimir Kaiser, a lecture on the development of the multichannel audio by Polina Khatsenka and a lecture on the digitization and archiving of analog media (shellac records, wax cylinders, tape recordings) by Filip Šír.

In addition to the live presentations by the invited artists, a compilation of the compositions has been created and will be officially launched at the closing event on Tuesday, 13th of December. The compilation is the second release on our newly established label, which can be found at → bandcamp profile.

All events take place at the House of Arts Ústí nad Labem. The project is financially supported by the Statutory City of Ústí nad Labem.

phonon~ association would like to thank Petr Karlíček, the director of the Archive of the city of Ústí nad Labem, for the exceptional opportunity and cooperation.

Polina Khatsenka

~ lecture on spatial audio in english

Polina Khatsenka is an audiovisual artist, sound designer and sonic curator from Minsk, Belarus, based in Usti nad Labem, Czech republic. She is devoting her work to various aspects of sound with a focus on audio performance, site-specific installations and composing. Polina is currently getting her Master degree at Jan Evangelista Purkyně University in Usti nad Labem, time-based media studio under supervision of Daniel Hanzlik and Pavel Mrkus.

Starting the work with spatial audio in 2018 during exchange in HSDusseldorf, Polina continued her research in Kunstuniversität Linz, where she leads a “Silence. Pause.

Together with phonon~ crew, where she is one of the founding members, Polina organises events, mediating experimental electronic, electroacoustic music and sound art in quadraphonic and octophonic PA.


Moisés Horta Valenzuela

Moisés Horta Valenzuela AKA hexorcismos (México, 1988) is a sound artist and electronic musician from Tijuana, México working in the fields of computer music and the history and politics of emerging technologies. His practice attempts to disrupt dichotomies with new radical juxtapositions, such as utopia with dystopia and folk traditions with capitalist modernity.

As hexorcismos, he crafts an uncanny link between ancient and contemporary sound technologies so as to address the politics of colonization, occupation and contemporary alchemy. Prehispanic sound artefacts from ancient México, Deep Neural Networks, wearable brain-computer interfaces and hand-crafted electronic instruments are critically merged together to situate the listener in a teknoXamanistic ritual of rhythmical and mnemonic noise.

Whether it be on dancefloors, in interactive immersive sound installations, or in open source workshops about AI and Machine Learning and discursive programmes; his work has been presented at Ars Electronica, Linz (2020), MUTEK AI Art Lab Montréal (2020), MUTEK México (2012), Monom 4D Sound Berlin (2019), CTM Festival Music Makers Hacklab Berlin (2018), Rum/Klang Galerie Denmark (2018) and ElektronMusikStudion Stockholm (2017), among others.


Jan Krombholz

Jan Krombholz is an audiovisual artist, DJ and teacher based in the Ústí nad Labem region. His work focuses mainly on site specific (sound) installations, group A/V performances (phonon~ crew, Auxig) and spatial aspects of sound. Currently, as part of his doctoral research, he focuses on the implementation of the medium of sound in art education.


Antje Meichsner

Antje Meichsner / Shannon Soundquist is a sound artist and radio producer. She holds degrees in art history, psychology, communication studies, and studied media art with Carsten Nicolai / Alva Noto, currently with Nevin Aladağ. She works conceptually with sound, text, graphics and typography. 

Her live sets are cinematic, dark, noisy, non-tonal and conceptual. The sound works are based on the de- and reconstruction of body sounds and speech material that poetically revolves around the subject’s condition in society. Her works are both installation / radio play and performative. Her research question on sound is: How can body sounds and speech be morphed into abstract electronic sounds and vice versa? What does the boundary of understanding and meaning feel like?


Jan Macháček

Jan Macháček (aka Ancestral Vision) is a Prague-based producer, DJ, sound designer & co-founder of hybrid electronics label and radio show Unizone.

His music is a deep melting pot of hybridised club forms, self-collected field recordings and both alien and organic textural sound design. Glitchy percussions amalgamate with heavy drones, resonating breakbeats, liquid textures, sampled choirs or advanced vocal processing. It is therefore not surprising that he loves bold emotional melodies and soothing soundscapes the same way as rusty drones and jaw-breaking kicks. All of these elements are traceable in both his production and mixes.

Ancestral Vision is often shifting gears between genres, rhythms, tempos and moods, sometimes even within a single track. Even though he has been focused in recent years on self-releasing of singles, his works could be also found in the discographies of labels like Club Late Music, JEROME, DESTITUTE, Oramics, Red for Colourblind, hyperlink or Unizone.

He debuted with his live set at Lunchmeat Festival in September 2022, where he did audiovisual collaboration with visual artists realitycongress & h5io6i54k.
