William,
There is one band that does Cajun music. If you're interested, you should check them out.
Grouillant Gumbo.
The contact is Harlan Johnson. Let me know if you'd like to have his coordonates. I played with him in Mtl a few weeks ago in a private jam session. I haven't seen the whole band in action, but he's an excellent Cajun box player and singer.
