This is Old-School Black Metal with good Darkthrone grooves and a cold, frigid heart.
The production is underground and raw whilst still retaining a power and presence; it fits the band perfectly and recalls a golden era of the style.
Vocally we have traditional Black Metal croaks, rasping out blasphemy and hatred with relish. Again, like the production values, it suits the band’s aesthetic to a tee and the delivery never slips.
The songs are traditionally composed and use winding melodies to add atmosphere and Blackened intent. The rhythms are dark homages to all that is evil and the riffs seem to circle malevolently like waiting carrion feeders.
If you enjoy largely mid-paced Black Metal with a grim melodic sensibility then I would definitely recommend Demonic Slaughter to you.
A very good listen indeed. Bring on the darkness.
