A unique loudspeaker constellation creates a virtual, "kaleidophonic" acoustic. Vertical vortex movements are the basis for the projection of various sound experience spaces, which are perceived as a constantly breathing sound stream. The sound stream is based on a weekly composition. This reacts on seven different listening levels to the events in the surroundings and is changed and designed live by musicians. In the dynamic sound stream, the musicians perform live with their own instruments.
The capsule serves the musicians and sound architects as a "concert ditch" at a height of three metres. It can be opened and closed like a cocoon. The ceiling becomes a stage when opened.
The artistic concept of sound architect Andres Bosshard was planned and realised in collaboration with OOS, sound specialists and musicians.
