Montréal stalwarts Joane Hétu (as, vcl) and Jean Derome (as, flt, perc, vcl) combined song forms, ragged improvisation, and playful theatrics for uneven results. Derome augmented his alto and flute with his usual bag of bells, birdcalls, toys, and even a megaphone for contrasting textures to Hétu’s unpolished alto and cracked, squeezed, and choked singing. There was always a sense of personal play to their set but, too often, it carne off as forced theatrics. The presentation of the Edmonton duo of Laura Kavanaugh (video, sampler, electronics) and lan Birse (electronics) was diametrically opposite to the raw theatricality of Derome and Hétu.
