Consider me both interested and a traditional sean nos singer(as much as a well-melted American can ever be such). Whether or not I do an old style authentically probably depends on who you ask(and I'll leave it to others to decide). I have spent more energy in the last few years finding an unaccompanied style that feels both traditional and LIKE ME, rather than worrying about whether it sounds like someone else. Only because that's what I wanted to be about, not because I have any itch with striving for truly traditional sounds as embodied by great singers.
Although a good deal of my repertoire is Irish I am probably more akin to traditional acappella English singers, ala Louie Killen, Martin Carthy, and tons of others. Am also heavily into Shantey singing so Stan Hugill has been a big influence in person and in writing.
I'll give some more thought to singers I believe in! Marc
