Query: Great first part, second part disappoints in long term

Following the traditional pattern of a requiem, the firt part of this contemporary requiem is the most thrilling and exciting part of the album. Preisner perfectly knows how to build up the tension towards the end. The vocal parts are very strong, here and there the orchestra sometimes sounds a bit shaky. The second part is interesting to listen to, but wears off very rapidly. Serves fine as film music or back ground music if you can't be bothered to listen carefully, but does by no means live up to the expectations raised by the first part. My four-star rating is based on the first part only. Preisner should not have bothered about the second part.
