Carl Michael von Hausswolff, Swedish composer, visual artist and curator, is considered one of the referential figures in the field of performance audio and radical music. Developing his research on the physicality of sound, he makes use of video, tape recorders, radar and sonar exploring electricity, frequencies, architectural spaces and paranormal electrical interferences. Always interested in the phenomenon of EVP (Electronic Voice Phenomena, voices from other dimensions intercepted as audio frequencies recorded to tape) von Hausswolff works to bring hidden elements to light. A past collaborator with The Hafler Trio, he is a veteran of the electronic music scene for more than twenty years and has collaborated with, among others, Erik Pauser, Leif Elggren and John Duncan.
