Duister means Darkness in Dutch. Darkness: that's precisely where those three tracks come from!
Dark, hard, relentless, industrial-tainted, repetitive, scary. Three smoking hardcore monsters hovering around the 180 bpm area for this obscure release. Their only weak point is the relative monotony of the kickdrum.

Gabber did not kill hardcore as some might say: it only forced hardcore relying on quality to avoid becoming cheesy.
This release is a proof that hardcore is still doing well, thank you very much!
