Mary Bergin was born in Dublin in 1949, and starded playing the whistle at the age of 9, after hearing Willie Clancy (Uilleann Pipes) in concert. She moved to Spiddal, where she still lives today. She plays with Alec Finn (De Danann) and the group Dordan, and teaches the whistle.
She has recorded 2 solo albums, the first with Alec Finn and Ringo MacDonagh, and several albums with Dordan. Her style is rapid and highly ornamented, while staying fluid and subtle.
