“Lament of the Three Marys”, by Iarla Ó Lionáird.
(If you enjoy this, I heartily recommend his solo album The Seven Steps to Mercy (Iarla is also a member of the Afro Celt Sound System, fusing modern dance rhythms (trip-hop, techno, etc.) with traditional Irish (Celtic) and West African music).
My sons are fans of an Irish band that plays clubs in NYC: Shillelagh Law.
