[Article Summary] Louis Dufort’s videomusic piece Épochè, presented at Montréal’s Elektra Festival in 2008, encapsulates his experience of sound as duration and movement in space. The video, created in 3D programming, and presented on a huge screen, features music comprising transformed and abstracted brass sounds, sometimes massive and sometimes ethereal. His newest recording, Matériaux composés, is a DVD-Audio disc featuring 5.1 surround sound, which provides a three-dimensional listening space for the home listener. Dufort has collaborated with choreographer Marie Chouinard, creating major works which have received international recognition. He is also a member of Montréal Sound Matter, an artist collective that has produced several concerts and sound installations. He increasingly feels drawn to the sounds of acoustic instruments, inviting musicians to record in his studio. He has composed works for Quatuor Bozzini, Quasar saxophone quartet, and Ensemble de flûtes Alizé, among others. For Dufort, music is an aural and experiential phenomenon with links to the oral tradition of story.
