I will agree with most here that Out Of The Silence is the best. But I will disagree with most and say that there is nothing boring about the more Celtic tinged albums, particularly Belief. Just because its slower, atmospheric and evocative doesn't mean for a moment that they aren't very good albums. Belief has some awesome songs on it and Arc of the Dawn isn't half bad either. I never got on much with Blood From Stone.
