Empties-Impetus attempts to navigate the instruments of the string quartet as imaginary interior spaces and as bearers of meaning; variously by grappling with the historical weight of the idiom and the recognizable quality of its timbres, and also by subverting that meaning by reassessing the objects according to their physical construction, spatial properties, and different environmental contexts.
Empties-Impetus was realized in 2014-15 at the composer’s studio in Montréal (Québec) and completed in 2015 in the studios of the Groupe de recherches musicales (GRM) in Paris (France), and premiered on January 24, 2015 as part of the Multiphonies series presented by the Ina-GRM at the Auditorium Saint-Germain of the MPAA (Paris, France). The piece was commissioned by the Ina-GRM. Empties-Impetus was finalist in the 2nd Klang competition (Montpellier, France, 2015).
