A neat lesson in switch flipping right here as Macabre Unit Digital follow up Demon's deep n' deadly "Frostbite" with this cheek-slapping trio of grooves from New Zealand duo Perverse. The title track is a precision-built stepper that segues smoothly into a halfstep mid-way. If you're keen on squeezing more energy from your dubstep then look no further than "F King Insanity"; blustering with tight drum patterns and nagging stabs, it's hard enough to make most techno fans blush. Finally we hit "Cryosphere": leaning more towards the label's deep signature, this moody backdraft is likely to stir up all sorts of dancefloor casualties. Watch out; this "Epidemic" is likely to catch like wild fire!
