Larger than the former group and more obvious in its use of strings, percussion and electronics is Montréal’s Ensemble SuperMusique (Ambiances Magnétiques AM 239 CD actuellecd.com). The tracks on Les porteuses d’Ȏ are also less homogeneous than on other discs. Although these single compositions by ensemble founders, percussionist Danielle Palardy Roger and saxophonist Joane Hétu (plus one from Vancouver’s Lisa Cay Miller) utilize a mixture of notation and improvisation, the results are undeniably divergent. Ostensibly about Canadian drinking water rights, Miller’s Water Carrier is multisectional, with strident tutti interludes. Otherwise, the narrative depends on contrasts between upbeat concert band-like melodies from the horns and Guido Del Fabbro’s delicately formal violin elaboration, with the churning rural landscape characterized by Bernard Falaise’s clanking guitar effects, plus primitivist slashes from Alexandre St-Onge’s electric bass and electronics. Additional strength is given to the track’s political message by repeated scrapes on bare acoustic strings plus Ida Toninato’s gusty baritone saxophone. Describing a journey among the planets, Roger’s En arrivant par le nuage de Oort uses electronic crackles and pops to underscore the extraterrestrial journey. With echoing percussive swats from her kit and that of Isaiah Ceccarelli, rugged reed smears and sprung sul ponticello pressure from Del Fabbro, violist Jean René and cellist Rémy Bélanger de Beauport, plus some snarls and growls from trombonist Scott Thomson, the composition reflects the energy and turbulence of the heliocentric world. And like the predicted end of the universe, the tremolo piece doesn’t climax, it just ends. Based on mumbled vocalese, Hétu’s Préoccupant, c’est préoccupant is more problematic since her gargles, whoops and whines are often incomprehensible. Melodramatic and dissonant string section swipes, guitar flanges, buzzing wave forms and unfocused drum beats contribute to the verbal commotion, rather than framing or defining it.
