I agree with Philippe's recommendations for fiddlers here (the ones I own,
Noel Hill and Tony Linnane, with Alec Finn
Frankie Gavin & Alec Finn
Frankie Gavin & Paul Brock: Tribute to Joe Cooley
Kevin Burke: If the Cap Fits
and would also add anything by Andy McGann, particularly
Andy McGann & Paul Brady
Ancy McGann & Paddy Reynolds.
The "Jackie Daly and Seamus Creagh" recording, one of my favorites, is indeed
available on CD (as is everything else I've mentioned).
And yes, early Chieftains, the first four, plus Bothy Band & DeDanann.
