Ho, ho, hoMy favourite would be a toss up amoung these 3
Vince Guaraldi Trio - A Charlie Brown Christmas. Because it makes me spontaneously break into the "Peanut gang dance/twitch/shrug"
Don Ross - Wintertide (Guitar Music For Christmas) . Because his ability and artistry blow me away.
Bruce Cockburn - Christmas. Because of his ability, a great selection of tunes, and his refreshing/genuine approach to them.
Listening to all three of these just make me feel good.
Be well. JK
