Ireland, I suppose, like anywhere else with traditional music.
If you are a lazy tourist who wants to be 'entertained', you will end up listening to 'ersatz folk' designed to draw you in to buy something
If your interest is genuine, you have to either pre-plan or make the effort when you arrive.
Dublin for instance, has both - probably a predominance of the former.
This particular one-street town on the West Coast, is a traditional-music friendly one where you can find good sessions four nights a week, rising to around six in the summer months.
We tend to send the casuals elsewhere, usually Doolin, which tends to cater for tourists who wish to listen to each other rather than what the locals have to offer.
Nobody has designed a bodhran/free notice yet, but we're working on it!!
If you wish to hear good music, you need to remember that it's what locals do for their own entertainment, not for yours - the "entertain me" attitude may work in the cities, but not necessary in rural areas.
I write as a 'blow-in' who first came here over forty years ago looking for singers and moved here permanently eighteen years ago because we found some.
The locals tend to be far more polite than I am - occasionally, after a few spoiled sessions, I wish they weren't.
