Both versions are stormers with the trance-like swirls all through and the signature Kevin Energy pacing. The original mix is more dark and brooding but still enough bounce to it to move your feet, it's well sequenced and the transitions from build-ups to breakdowns are as seamless as you'd expect. Samples taken from Dead Can Dance - The Host of Seraphim.

(The vinyl has definitely seen better days, this club busting weapon has been deployed in many a underground situation and has the scars to prove it.)
