I have had this CD set for years now. Peter Schreier leads the Rundfunkchor Leipzig and Statskapelle Dresden. I listen to it at least twice every Christmas and it never fails to delight. I have not found a better performance yet. It has good tempo without being too fast. A very German performance of German music. Ofcourse you can listen to the samples.
Modern instrument performance in the best possible taste. German cast (nobody plays Bach better than the Germans) which would be hard to beat... I have 7-8 recordings of the Christmas Oratorio, and this one I cannot recommend enough.
