To The Nameless Dead is an epic combination of Celtic, pagan, folk and black metal. Primordial takes the listener through valleys of sparse and majestic melodies, up the mountain with steady and powerful riffs, and down the other side with dark, intense black metal. The songwriting is outstanding, with layers of thick guitars and subtle atmosphere that ties together the lightness of Celtic/folk metal with the majesty of pagan metal and the bleakness of black metal.
Vocalist Alan Averill, aka "Naihmass Nemtheanga" is able to croon melodically, sing with a more aggressive style, and do harsh vocals with equal skill. To The Nameless Dead is one of those really good albums that draws you in and envelops you, making you feel like you're listening from the inside out instead of the other way around.
