Powerful track this... that riff is
seriously nagging in content (too much for me

- whadya mean 'wuss'? ! :briggin: )
I do like the piano after the break complementing the theme and the filtering shortly afterwards to end the track - - good outro
This is probably your final edit but I reckon you could twist that nagging riff into something else a couple of times along the way, to chop any monotony that may occure (for some folks anyways!), summink simple but effective...
Definitely a track for the tougher of cookies...:exclaim: :exclaim:
