The choral chamber group Anúna first entranced public-television fans while performing as the black-robed choir in Michael Flatley's Riverdance. Under the guidance of brothers Michael and John McGlynn, Anúna has become a sensation in its own right, blending elements of world, classical, and traditional Irish music to hauntingly beautiful effect. Borders is the exclusive retailer of Celtic Origins, the companion to the group's public-television special that features music whose origins may be Irish, but whose appeal is universal.
