Dietrich Buxtehude wrote two organ pieces about the famous Christmas hymn 'Gelobet seist du, Jesu Christ'. BuxWV 188 is an extended Fantasia and BuxWV 189 is a short chorale prelude. I went for the festive interpretation regarding tempo and registration. Although this Metzler organ of Poblet hasn't the typical North German organ sound, I love how Buxtehude sounds on this organ.
