Working with Roscoe Mitchell on his project with the Montreal - Toronto Art Orchestra I was exposed to a number of Canadian musicians who should be known better outside of Canadia. Initially, the most striking is Yves Charuest. Sadly, he currently doesn't have any recordings available, but you can get a bit of him, as well as the fine bassist Nicolas Caloia at this site: http://musiquerayonnante.org/charuest-caloia.html.
I hope to mention more of these fine artists in the future if anyone cares.
