The Nuckelavee boots things off with speed and chilling minor-key melody, a la Swedish maniacs Nifelheim, before I, The Deciever's chorus goes full black metal, and the immaculately-titled Goat Vomit Nightmare brings in a punkier punch.
All of which might seem easy to do, and with a little study of your chosen source material one might make a good fist of writing one or two songs in similar style, but to deliver something as consistent as Hellripper do is a damned sight harder. Especially when they do it with this much untethered, frothing energy that fires out of every windmilling riff and lightning-bolts-from-the-fretboard lead.
If thrash should be anything, it's exciting. Hellripper do this. And, fast and hard, creative while showing its roots, genuinely thrilling, Warlocks Grim & Withered Hags is the best offering yet from a truly brilliant band. Your move, Metallica.
Verdict: 4/5
For fans of: Nifelheim, Metallica, Midnight
