im not sure if this will be of any help but you might like the track VNV Nation - Standing. Its grouped in the industrial category but it sounds total dark trance, with vocals that fit perfectly over the music. Its a really existential song, not sad, not happy. The whole album that its on, empires is just amazing.
this review from amazon sums up the album to me :
"Suppose that all of the greatest euphoric heights of trance were cast into a concentrated area of anguished emotion. Then suppose that this mixture was fired through with electricity, and then shot on a beam of light into the setting sun. Upon impact, the wave created would be... The sound that comes out of the speakers whilst this CD spins."
