Any trip I've ever taken over the years, I've missed big festivals by a day or two...grrrr...However, we've been to West Clare on several occasions & there are wonderful traditional music seisuns in the pubs of Doolin, not far from the lovely Cliffs of Moher. In Dublin, especially on a Sunday morning, go to O'donohue's pub. They have a front & back room- one has musicians, the other ballad singers. Do try to get to the west...its enchanting. The 2 pubs in particular in Doolin are O'connors & McGann's. We prefer McGann's. have a lovely trip! I've heard in mid-february all the musicians gather in Doolin- informally. An acquaintance goes every year. He used to work at McGann's, so knows the 'craic.'
