We are already half way through Advent but PollyEster sent us a great tip about the Musical Advent Calendar concerts going on every day up to Christmas. You can see the list of concerts here  – they range from classical, rock, choir  to brass bands. Entrance is free (you can give donations on your way out).  Many are in the Altstädter Nikolaikirche so very convenient for the Weihnachtsmarkt too.
