Not a favorite Christmas harp CD, but my Christmas/Advent/Liturgical playlist on YouTube. I searched YouTube for my favorite carols and selected my favorite version or versions, several of them with harp accompaniment:
Es Ist ein Ros’ Entsprungen
Maria Duch ein Dornwald Ging
Minuit, Chretiens (O Holy Night)
O Come, O Come Emmanuel
Once in Royal David’s City
The Boar’s Head Carol
Leise Rieselt der Schnee
Stille Nacht (Silent Night)
I have also played or attempted to play all of these myself
