Advice?

[Rambis]

I am headed over to Ireland in April and wanted to know if anyone had any recommendations?
I am a big Irish traditional music fan (main reason I want to go) so I am headed to the temple bar area of Dublin for a couple of days. I am thinking about the Paul Brady concert in Limerick since I will miss the Galway and Waterford shows by a couple of days. What I am really looking for is a place like Dingle but the dolphin seems to have made the place a bit touristy is that the case? I have heard good things about McGann's pub on the west coast. My folks ran across Altan there a few years ago and I would love to see them at their local. I had a chance to see them in Chicago last year and they were almost as good as Danu. I have tickets to see them two nights in a row in Cedar Rapids Iowa next week.
I am a bit worried that since I have heard about some of these places they might be tourist traps.
I just want to sit down with a good pint and relax to some good music period.
Any information would be much appreciated.
Slainte!
