This video is pretty old. The conductor, Nikolaur Harnoncourt, has quite a few more miles on him these days, but he’s still The Goods. He’s made it his specialty to re-create music using original instruments wherever possible, so what we get to hear is as close as we’re likely to get to what the composer would have had in mind.
This is the first movement of the first cantata of the Christmas Oratorio. The final movement of the sixth and last is here (I just shoved it in because the trumpet is Ludwig Güttler, who absolutely rocks; the video shots are in Transylvania):
I may have pasted either or both of the above videos here before, but if I have, so what? It’s my blog, after all.
