Rincon Roy, Alistar Anderson is a major exponent of the concertina up here in Northumberland , he was i think a member of the 'High Level Ranters'and he is also well known for his pipe playing you should also check out Kathryn Tickell if you like the sound of the Nortumbrian pipes.

Hope I'm not messing the thread up...sorry.

love and happiness
