Tanya St-Pierre is a Graduate in visual arts from UQTR (Université du Québec à Trois-Rivières, Qc, Canada). Philippe-Aubert Gauthier is a self-taught sound artist, a Ph.D. in acoustics, and a researcher in acoustics: spatial sound and sound environment reproduction (Sherbrooke's University).

Both artists presently work and live in Sherbrooke, Quebec, Canada. Each artists have a solo practice but they also combine their specializations for large-scale visual and sound installations. Their collaboration began in 2000 and they started making performance art as Noïzefer CWU in 2004. They now mostly perform in sound art and experimental electronic music events. Works have been supported by the CALQ and CAC and shown in divers contexts in Canada, the United States, Maroc, Mexico, United Kingdom, Germany and France.
