Their music combines dub mixing techniques with extreme noise performance and psychedelic walls of sound with harsh static rhythms. The use of cassette decks features heavily in their work, using home-made collage tapes as well as found ones. Smashed and grabbed cuts from warbled and detuned tape are juggled with blown out beats and lo-fi sampling. Performances are filled with volatile energy and unpredictability, never the same twice and constantly evolving.
Holzkopf has been actively performing in North America since 2001 and Europe since 2006. Concerts have ranged from Estonian industrial festivals to jazz and new media festivals to squat shows and parties on farms and under bridges. Their work is adaptive and based on improvisation, proving itself in any situation and expanding itself based on new contexts. They have supported a diverse range of artists from free-jazz drummer William Hooker and DJ Olive to Venetian Snares, Cex, John Oswald, Scanner and noise artists Knurl, Emil Beaulieau and many others.
Holzkopf has produced dozens of small run CDs, tapes and records as well as many online releases. Their work has been released by labels such as Wintage Records & Tapes, Panospria, Eschaton Industries and Dainty Deathy in Canada, Attenuation Circuit and Toztizok Zoundz in Europe and No Disco in Japan. 2014 will see the release of a new tape on Europe's Third Type Tapes label as well as a self-released 12".
Their artworks focus on two dimensional collage and linear video as well as video instillation. Their experiments with stop-motion and creating glitches through batch processing were explored through a residency at Les Pixels Transversaux in Sevres, France in 2010 with a completed work entitled "Foreign Heroin" screened at Les Generale En Manufacture in Sevres as well as Soundfjord Gallery in London, UK and Blim in Vancouver, Canada. Holzkopf has had various experiments with analog feedback and unrestrained digital glitch worship screened at VIVO Media Arts Centre in Vancouver, Canada as well as part of musical performances at the Centras Festival in Lithuania and the Montreal Fetish Fair among other events.
Holzkopf is currently the resident artist at Hammock in Vancouver, Canada. They are working on group audio collages and a zine about a cross-Europe tour in 2011.
