The internationally renowned Celtic Irish choral group Anuna - the original vocal group in Riverdance - bridges the gap between classical and popular music with its pure, haunting, emotional, mystical and unusual sound. In a new special, the singers, musicians and dancers of Anuna perform popular and lesser-known Christmas music and reminisce about their most cherished holiday memories. Taped in front of a live audience over the course of two nights, the songs and performances combine dramatic candle-lit sets, crystalline voices, ethereal costumes and ritualistic movements. Anuna's previous public television special, 2007's Anuna: Celtic Origins, spawned a national tour and a best-selling CD, which remains a presence on the BillboardWorld Music Charts.
