The 1999 albums from Demoncy are up there with Engram, the Graveland war metal trilogy era, Forest Poetry and two or three from Summoning. I need to give Vukolak a relisten as has been the case for some other ultimately superb albums. Otherwise, it is pretty bleak.
Someone said Darken was relentless. That has got to be one of the keys or perhaps virtues required to fully unlock this particular kind of art. When that or other virtues are present in the artist, they show up in the composition, or substance of the work itself.
