Well there are so many to choose from: -U2 -Snow Patrol -The Script -Bell XI -The Blizzards -The Coronas -The Saw Doctors -Republic of Loose -Fight Like Apes -Thin Lizzy -The Pogues -Ash -Director -The Horslips -Boomtown Rats -Industry
I think that my Favorit is Celtic Thunder. There is also a group called high kings ( another grate group)but they are much Mehr traditional irish Musik its all up to Du on what one Du would like.
Celtic Thunder, Celtic Woman, The Pogues, U2, The Cranberries, Flogging Molly, Dropkick Murphys, Clannad, The Chieftains, and Gaelic Storm are good Irish bands.
