Thanks for replies everyone. I'll just be going to visit a friend of mine who moved there two years ago, but isn't into music much. I'll be spending a good amount of time on my own, so thought I could catch some shows.

I believe the Saturday market is still taking place, and someone told me they have music there.

I'm more of a jazz fan myself, but my travel companion (who won't be staying in the same place as me) is a died in the wool folkie.
