Music...sound...noise... They all intersect in a new festival of experimental performances, live electronic music, audio-visual works and sound installations. Aotearoa Audio Arts is being hosted by Victoria University of Wellington's New Zealand School of Music and it's bringing over some international leaders in the field of sonic art. One is Canadian Nicolas Bernier, an award winning audiovisual artist who invents new kinetic instruments that he plays using computers rather than by hand. Lynn Freeman spoke to him and to another guest speaker, Mo Zareei who lectures in Sonic Arts & Engineering at Victoria : The Aotearoa Audio Arts Festival in Wellington starts on Thursday.
