Two excellent CD's from traditional musicians that I like are;

Waterson:Carthy "Holy Heathens and the Old Green Man" I got it at the weekend and was playing it in the car today - an excellent album; newly issued, I believe.

Magpie Lane "WASSAIL! A Country Christmas" One I have had for some time and must put in the car.

These are both very much traditional music albums but not what most people would think of as "Traditional Christmas Music"

Both have interesting versions of well known carols with a particularly attractive tune for The Holly and the Ivy from Herefordshire which I have been meaning to learn for some time but have never got a round tuit!
