Actually we had a thread on this a little while back if your interested
http://www.cluas.com/discussion/topic.asp?TOPIC_ID=2141
But I'm glad you brought this subject up again because it gives me the opportunity to mention a few other gigs I didn't mention in that thread.
Most recently Schneider TM in the Red Room Cork and The Skatalites in the Half Moon (Cork Opera House). Most Suprisingly good gig of the year was the Waterboys in the Cork Opera House, I would not have normally chosen to go to a gig like this (I just went along with my sister who is a big fan), but I was blown away by how good they are live.
As great as those gigs were, Chicks on Speed in the Triskel Arts Centre still stands out as the best this year.
