The 18-limbed Space-soundInstallation LOST (Fig 7) was staged with lighting and was created for rooms with high ceilings and long reverberation periods. It was first exhibited in 1992 in the light-well of the Badischer Kunstverein in collaboration with the ZKM (Centre for Art and Media) in Karlsruhe, Germany. The Space-soundInstallation is, above all, characterised by an approximately 7m high, 6-limbed loudspeaker column (Fig. 7, level A). Sound-masses plunge down over this Space-soundObject and pull themselves up again in specific phases.
When entering the space through the gallery in the upper floor the visitor is occasionally surrounded by a band of sound that moves across an enterable Space-soundBody in the shape of a 6-limbed loudspeaker-semicircle (Fig. 7, level B) and counterpoints the plunging sound gestures. The circumambulatory Space-soundBody of level C, which is positioned on the floor, mainly transmits fluctuating sound-colour priming coats (‘Klangfarbgrundierungen’) and forms the sound tableau for the moved sounds of levels A and B.
