Sietze de Vries is a Dutch organist and known for his ingenious improvisations. Joachim Scheufele-Leidig transcribed some of his improvisations and made those nice editions available. This piece on the Christmas hymn 'Vom Himmel hoch, da komm ich her' was one of the variations Sietze improvised on the organ of the Sankt-Martini-Kirche, Bremen (find the link in this description for all the variations en beautiful singing of the hymn verses between the variations). It's a pastorale-like piece with the cantus firmus in the pedal part, which makes it a piece with double pedal.
At the time of uploading this piece it's not Advent or Christmas yet, but I intend to publish some Advent/Christmas pieces earlier this year. So if you are an organist and found some of these pieces interesting, you have enough time to practice them for the Christmas season.
