Simple and straightforward, post great music! I know this has been done to death but I’d like to give a shout out or two.
Manran, an excellent, excellent Celtic group In this video they are dressed silly, but the accordion and flute are outstanding. They are worth traveling to see.
The gold standard for Irish trad, Solas. They are even more incredible live (if possible).
And the platinum standard is of course the Chieftains. If you don’t have The Chieftains 9: Boil the Breakfast Early, go buy it right now.
And of course one of the best trad tunes of all time, Arthur McBride as performed by Paul Brady.
