Jesu, Joy of Man's Desiring
I’m a little early perhaps, but I have pulled out some Christmas music (though this one is not strictly for Christmas). So, here is an old classic of mine, that never gets old and comes out every year.
You needn’t watch the video. But make sure you are still listening and ready to rise up out of your chair and begin to conduct your imaginary orchestra at about 1.42. Then I love the section from about 3.22 onwards. It’s pure Christmas euphoria. And the brass from 4.00.
