Marko Košnik has been active as a polymedia artist since the early 1980s. He composes electroacoustic music, develops synesthetic instruments for manipulating sound and live digital video, directs and produces performances ranging from solo to group works, and builds poetic platforms and installations that he augments with social and technological layers, extending into interactive environments—preferably programmed by himself.
Among the most important projects / performances / installations / appearances he has produced or participated in are: Stvar - The Thing (premiere, HFBK Hamburg, 1991 – Cankarjev dom, 1992), Opna 2 - Membrane 2 (premiere, Ostranenie Festival, Bauhaus, Dessau, 1993), Cukrarna (premiere, Media Biennale, Leipzig, 1994 – Cankarjev dom, Kapelica Gallery, 1995), A.B.Sence (Cankarjev dom, 1996 – New Moves Festival, Glasgow, 1997), Parahouse (Ostranenie Festival, KIEZ Cultural Centre, Dessau, 1997), PA-RA, a performance for six performers (Cankarjev dom, 1998), 5 Synesthesias for Sound and Moving Images (Kino-uho, Slovenian Cinematheque, 2000), Desktop Cinema (Kino Reitschule, Bern; Kino-uho, Slovenian Cinematheque, 2000), Theothea (SKC, Belgrade, 2001), Operabil Kobe (Kobe, Maribor, Berlin, 2006), the opening performance of the Transmediale festival (Haus der Kulturen der Welt, Berlin, 2008), the Electropera series of projects (Vienna, Rijeka, Istanbul, Abrantes, Berlin, Helsinki, Mooste, Maribor, Ljubljana, 2008–2011), Apres MIDI (a performance for two robots and two female performers, Kapelica Gallery, 2014), Zborogled (a live transmission of security-camera feeds of Kino Šiška, with numerous lecturers, 2015), STWST – Unfinished Business (performance at an accompanying event of Ars Electronica 2019), Map of Errors (KIBLIX, Maribor, 2023), and TAZ – Temporary Autonomous Zones (Exhibition Performance of the City, MSUM, 2025).
In 1992 he produced the first interactive satellite program to reach 3SAT from Slovenia via Van Gogh TV at Documenta in Kassel, and in 1997 the first multi-directional netcast in Europe with the Berlin-based group XLR (Radio Študent, Kapelica Gallery). In 2000 he organized the hEXPO festival, which, with the help of 70 international guests, connected 14 co-producing locations across Maribor, Ljubljana, and Koper for three weeks. The regular program “Egon March Institute Presents,” which he hosted on Radio Študent (1992–1996), grew into the Free Media University (MUU), through which he initiated the Ministry of Experiment (RŠ, 1997–2000).
Through the Egon March Institute, which he founded in 1986, he has realized 72 productions up to and including 2023, 28 of them international, with more than thirty international collaborators in sixteen countries on the European continent, as well as in Mexico, Japan, and Indonesia.
