poltergeist:
a noisy usually mischievous ghost held to be responsible for unexplained noises (as rappings)
The installation consists of several identical units, each holding an electromagnet used as a hammer that hits the surface it is placed upon. Our version at De Singel in Antwerp consisted of 13 such units, but depending on the location this number can vary. The noises that are generated by hitting the surface are the reflection of rhythmical principles and algorhythms generated by the program controlling the units.
Due to the physical placement in a wide configuration the rhythms also literally converge with spacial structures and movements. At times you literaly see a rhythm transplant itself along the units and displace itself in the space. Rhythmically the installation ranges from complex polyrhythmical structures to straightforward grooves, and all are generated in realtime, practically excluding the chance of literal repetitions and predictability. Every unit also holds its own piezzo element, and amplification system to make the sounds more prominent if needed, while at the same time keeping the natural spacialisation of the soundsources.
