Soundscape from Signal-Recordings of Bats by Lasse-Marc Riek (D)

Field recordings:
Since May 2003 location shouts and social sounds of bats were collected by means of stereo-microphones and ultrasound-detectors. Social sounds such as the communication between a mother bat and her child can be heard by the human ear. Location shouts, used for orientation and hunting, are in the range of ultrasounds and can’t be registered by people. The sounds of the bats were recorded during excursions in cooperation with bat researchers of the “Naturschutzbund Kreis Segeberg” of the following species: Pipistrellus, Nyctalus, Eptesicus, Myotis.

Detector:
The machine transforms the inaudible ultrasounds (sounds higher than 22khz) in audible sounds. In real time recordings you hear clicking sounds and by means of slow or fast motion these sounds are transformed in wet or dry chirping or twittering sounds. The recorded material was analog and digitally edited, arranged and converted into a composition.

Compostion:
Sounds, recorded by chance, a minute in a busy shopping area, the high whistling of a stone-saw, the to and fro of buses, the scraps of conversation of people passing by, the sounds of ringing mobile phones, doors and traffic lights, the barking of dogs and the singing of birds turn into a score. The sounds of the streets were replaced with the transformed bat material, according to rhythm and pitch.

RGB-Hypnosis by Britt Kootstra (NL) & Arvid van der Rijt (NL)

Daily routines are the object of my tableaux vivants. Within the familiar frame of a well-known routine the body moves, whilst the mind has the freedom to wander off and travel around the world. The movements are carried out on automatic pilot. Both the performer and the movements are caught in loops. The acts become strange as if repeating a very familiar word over and over again, until it starts to sound alien, as if taken from another language.
