Rechenzentrum are Lillevan (video) and Marc Weiser (music and composition). Within the past years the duo has released outstanding, highly acclaimed records in the wide field of experimental electronic music. Formed at the Documenta'97 exhibition, Rechenzentrum search for new processes of music/moving image production, while refining forms of presentation which create on-stage dialogue between audio and video. At the outset of Rechenzentrum they decided and defined our project as a "band" in which audio and video are equally important; we use video as an instrument, and they treat music visually. They release material in numerous formats, testing the possibilities and limitations of each, often involving cooperations with artists based in other media/genres, working with choreographers & dancers, the projected moving image being the only source of light on stage, all sound derived from live intervention.
