Nice stuff Brad. Used to be really into my dark growly trance.
Great atmospherics, pleasing stereo spread (on headphones, sounds lovely) and general nice menacing growl and development.
The main trance style synth I would want a touch more aggressive, seems to sit a touch further back in the mix in places than it should to my ears, like the section at the end, and maybe at the beginning as well... The only place where it really gets space to do its thang is around 1.23 and I'd expect it to really growl at you towards the end of the track.
Wicked atmospheric stuff though dude, great work. Sounds very polished, and you've seriously cranked some volume out of it. Might even be worth sparing the limiters a touch to give it a little more dynamic range.
