Living a couple of hours away from NOLA now but, I was born and raised there...always will consider it home. I saw this thread earlier and was going to suggest you go see some live local music (not necessarily at the "tourist clubs";Places like Maple Leaf, DBA, Cafe Brasil are better bets).
Kermit Ruffins would be great to catch, though I couldn't find any listings for him this coming week. I hope you enjoy your stay. Let me know if I can help in any way, or make suggestions. Cameron
