This is the stereo version of a sound installation presented at Montréal’s Studio Cormier in December 2004. It is the second part of the ‘’Ma chambre quand je n’y suis pas’’ series. The piece is based on the recording of “silences”, i.e. the recording of sound produced in spaces with no human presence. The sound of an “empty” Studio Cormier was therefore used as the material for the production of this piece. The sound takes were done during the quietest moments of the day, by means of microphones placed strategically throughout the Studio by the artist. The sounds gathered were then amplified, and their frequencies, accentuated to the extreme. In the installation itself, the sound was broadcast in multi channel mode over 11 loudspeakers, including a subwoofer, in four Studio Cormier spaces (“Hall”, “Living room”, “Bedroom”, “Lab”). This installation closed Mathias Delplanque’s Montréal residency at Studio Cormier from July to December 2004, as part of Les Inclassables program, proposed by the Association française d'action artistique (AFAA), in partnership with the Conseil des arts et des lettres du Québec (CALQ) and the Office franco-québécois pour la jeunesse (OFQJ). The result of the experiment, as presented on this record, constitutes a genuine drone odyssey playing on fullness and emptiness, presence and absence, ‘’speak’’ and ‘’non-speak’’…One long track full of subtle movement and enlivened with various underlying currents. A sheer delight. Mathias Delplanque is known, among others, for his releases under the LENA moniker on the Quartermass label. As THE MISSING ENSEMBLE, Mathias Delplanque, John Sellekaers and Daniel De Los Santos recorded the HIDDEN DOORS cd, released on MONDES ELLIPTIQUES (.E.Q.05.01.).
