You should to get in contact with Joel at
www.upstairsjazz.com. I know they've been doing this sort of thing for a while when they invite famous jazzmen from the states and make them play 2 nights in a row. Recently we had Bill Steward, Steve Kuhn and Steve Swallow.
Also, I'm pretty sure we could arrange a clinic like we did last year at l'UQAM or at my college.
