A weightier Canadian balance to the international sounds is the exclusive-to-VTO triple bill at the Tranzac club May 14. The Rent and Hat + Beard are locals, while Shaman from Montréal is also on hand. Consisting of Jean Derome and Joane Hétu on woodwinds, voices and objects Nous percons les oreilles Ambiances Magnétiques AM 200 CD exposes Shaman’s strategy of D-I-Y ethnomusicology. Like ancient tribal healers the duo expresses itself through verbal screams, squeaks, murmurs, mumbles and cries as well as inchoate instrumental textures. The two recount 12 short narratives which are as much Dada as primitive, wrapped in onomatopoeia that bonds mouth expressions such as cheers, yelps and gurgles with slide-whistle peeps, unsequenced altissimo saxophone stridency, key percussion, clipping chromatic timbres and reverberating body tube echoes.
