What happens when two classically trained musicians forego their customary instruments and get noisy? Martel’s viola da gamba is exchanged for static of unspecified origins, and Lauzier’s bass clarinet and sax are prepared and amplified to the point of feedback. Similarly, Tetreault forgoes LPs and focuses on the in-bred sound of his turntables’ motors and needle pick-ups. Far from formulaic, there are composers’ minds at work here, with gratingly engaging foreground phenomena emerging from background drones, concerto style. 8.5/10
