Frequenzwechsel started in 2008 as an intermedial exhibition concept and developed into an audio-visual improvisation collective consisting of composers, media artists and sculptors. Intersections of their collaborative space-based works include Instant Composition, Expanded Electronics, Videoorganism, Topographic Mapping. Don't Denoise!

As part of Lange Nacht der Museen, the artists' collective Frequenzwechsel presented a live electro-acoustic installation with video projections that make creative use of location data and its noise. The action extended over the entire evening, supported by the Stadtwerke Düsseldorf. With Tobias Beck, Tobias Grewenig, Volker Hennes, Matthias Neuenhofer, Ji Hyun Park, Martin Rumori, Susanna Schoenberg, Dirk Specht. Produced by Filmwerkstatt, Düsseldorf.

Frequenzwechsel performing at WDR Studio3, Wallrafplatz, Cologne.
As part of SoundART 2012, Frequenzwechsel has been playing on the 70 atavistic loudspeaker walls of WDR Studio 3.

Frequenzwechsel as part of COMPUTING MUSIC VIII performing at Kunst-Station Sankt Peter Cologne.
Tuba ventosa was developed for the organs of the Kunst-Station Sankt Peter in Cologne. The 23 minutes long sound and image composition is based on an audiovisual feedback via video, microphone and organ. The process is initiated by clapping hands, this impulse starts a video feedback by a randomly generated pattern. An edge detection algorithm modulates this into visual turbulence that controls the organs. Six different points of the video image generate data to translate the visual into midi data and correspondingly into notes. These, like the visual component, are structured in the compositional sequence by presets. The selection from the 120 possible registers, tempos and the character of the visual process are stored in these presets. The acoustic development via the microphone influences the parameters of the video feedback and thus the development of the visual turbulences. This complex system is controlled live on the basis of acoustic and visual programming and is accompanied by an analog application at the wind throttle. The video, generated in real time, is projected onto the floor in the centre of the church and into the vault of the aisle. A third projection, half overlapping the floor projection thrown onto the side wall, completes the performance space. Video recordings of the glass surfaces of the church superimposed by a visualization of the acoustic intensity of the sound event form a horizontal constant, dissolved in the top and bottom.

Frequenzwechsel performing on December 20th 2014, 7 pm - Piazza San Sepolcro, Cagliari.
A public performance/urban intervention by Frequenzwechsel based on a field work of 4 days through the city of Cagliari. The performance/intervention can be understood as a temporary polycentric sculpture made by the movement of different modules of action. The sculpture is going to take shape over some hours of a performance made of movements, recordings and evaluation of topographic, visual, sonic data —going to be recorded, transmitted, received. The city of Cagliari has been shown as an agglomeration of variable nodes. Locative data in particular (GPS coordinates) are used as a basic structure of this virtual sculpture with its center in Piazza San Sepolcro. With Tobias Beck, Tobias Grewenig, Volker Hennes, Matthias Neuenhofer, Ji Hyun Park, Susanna Schoenberg, Dirk Specht. A production by Noarte Paesemuseo.

Frequenzwechsel develops a flexibly configured and variably usable live set-up of electronic and electroacoustic
instruments together with video projections and luminous bodies, which are installed and played by the artist group in the space.

With references to topographical, historical and electromagnetic properties of the respective location, an improvised, sensory interactive overall sound in image, space, sound and light. With Tobias Beck, Tobias Grewenig, Volker Hennes, Matthias Neuenhofer, Ji Hyun Park, Susanna Schoenberg, Dirk Specht. Produced by Die Grosse, Museum Kunstpalast Düsseldorf.

Audiovisual composition of 1000 seconds duration with material recorded at room #002, former atelier of Joseph Beuys at Kunstakademie Düsseldorf. With Tobias Grewenig, Volker Hennes, Matthias Neuenhofer, Susanna Schoenberg. Produced by Teatro OUT OFF Milan.
