Verschränkte Spielräume (2015)

Concert installation for variable number of rooms, musicians and audience, interconnected through a Feedback Delay Network system

“Verschränkte Spielräume” – “Entangled Spaces” interconnects a variable number of musicians and rooms. Through the acoustic connections between the rooms and a feedback-delay network system, the musicians try to hear each other and play music. Every sounds in the rooms are recorded and played back by spatialized variable delay lines. The sound of the delay lines is physically mixed in the acoustic space, recorded by the microphones and played back again in a continuous flow. The resulted sound textures are unexpected and unrepeatable and can be interpreted as emergent phenomena of this non-linear complex feedback process. The gestures of the performers are extended in time, space and frequency, which are naturally interconnected by the feedback-delay network. The process can be theoretically interpreted as the scattering of sound inside a 10 kilometer wide multidimensional room, with its faces moving at variable speeds and creating transpositions through Doppler effects. Every sound inserted in the network will develop in a truly unique way into noise. Local networks are installed in every room but the central system distributes the delay lines randomly in all rooms, merging the acoustics of the various rooms, and creating an acoustic hyper-room. The audience is invited to move freely around the space and explore individually the dynamic process. The form of the piece is a hybrid between a concert and an installation. In the “concert mode” only expert musicians insert sounds in the network. In the “installation mode” the audience is free to interact with the network by producing sounds with their bodies, sounding objects or available musical instruments.
