Ghosthouse, I'm surprised that you liked "Bright Mississippi", but it encompasses many cultures and goes back a long way; a wide range of people like it, that indicates how broad that "Nawlins" thing is.
I just found "Ancient Future"; their music is akin to "Shadow Fax", I posted a few cuts before, now I'll see if I can find some new cuts to post.
This one is from the CD "Asian Fusion"

Enjoy the music.
