lot. They went to a couple of concerts nearby at night and hit up some museums, state capitol and other things during the day. Apparently there are some free museums nearby.
There are tons of restaurants with live bands. Some bars have three floors with a live band on each floor. One of my sons was telling me about standing in a place on the sidewalk and being able to hear the percussionists from five different bands at the same time. So, if you like live music, Nashville is a pretty cool place.
I can try to get some more info for you if better informed people don't chime in.
