George Winston's December was one of the first CDs we got after buying our first CD player. Solo piano improvisations on classic Christmas songs (at least, it sounds sort of jazzy/improvisational to me). We've been listening to it ever since. In looking for a link for it I see that there is a new 20th anniversary edition with additional tracks. I may have to check that out. I only have the original recording, but it is one of our (many) favorites.
