Maybe the previous concept of Gregorian was exhausted after four albums and something new was due - but even after repeated Listen wants not as good as previously liked me what has become of it. There's a reason why this CD is not "Gregorian V" is, but "The Dark Side". Only sometimes the usual worn and to dream enticing chorales come to train, often dominated wide Brushed Rock Sound with distorted guitars and pounding drums, only remember the voices in the of earlier times. It is not clear which target group to be served thereby. For the older generation, this type of interpretation is too hard for the younger ones the choir acts on antiquated. Nevertheless, this CD has its good sides. So the chorus has become more demanding and waiting times on with unusual for the normal ear sounds, but they are nevertheless very successful. And then there's the passages that are reminiscent of earlier times and reconcile one with the overly loud parts again. My tip: listen in, then decide!
