You may be interested in a couple of clubs that usually have live music: Tipitina's, Snug Harbor, and (depending on your sensitivity) a walk down Borboun Street. You can catch dixieland bands playing on the steamboat Natchez as well as in some of the larger hotels.
If you're interested in history I highly recommend the WW2 Museum, it's easily accessible by walking or streetcar between "Uptown" and the French Quarter. We have a very nice zoo and aquarium also. http://www.neworleansonline.com/
