Cathy van Eck, Sebastián Lach Lau and Paul Craenen are three composers who examine special themes in contemporary sound art. In 'A search for renoise' they explore the phenomenon of feedback, the whistling sound you get when you hold a microphone too close to the loudspeaker. Sebastián Lach Lau uses the computer as a compositional aid and bases his work on the interaction between a guitar, a computer and loudspeakers. Cathy van Eck goes one step further and manipulates the feedback by shifting plaster panels around. However, the passion for experiment is strongest in Paul Craenen, who sets to work with PVC pipes and plays with the absurd seriousness of the performance itself. 'A search for renoise' not only produces beautiful electronic sounds but also a light, humorous performance.
