I think that what you call "traditional" is a very subjective thing and impossible to define in terms of black and white. As an example I have noticed already in this thread that Paddy Glackin has been cited as a traditional player yet to me he is not quite a true traditional player. It is true that he has a great deal of respect for the earlier generations of players such as Johnny Doherty and yet his musical partnering (Donal Lunny and Jolyn Jackson) and therefore his musical aims somehow sit him just outside the tradition. A modern player such as James Byrne while stylistically similar to Glackin (thought technically perhaps not as perfect) is to me a "real" traditional player.
