Darkened Nocturn Slaughtercult is a German underground black metal band from Dormagen, Germany, founded in 1997 by Onielar and Ariovist. Today the band is made up of Onielar (voc, git), Velnias (git), Horrn (drums), and Adversarius (bass). They are a bit of a rarity in that they are a black metal band fronted by a woman. (Onielar's real name is Yvonne Wilczynska). DNS is playing a raw and fast version of old-school black metal, combined with Onielar's witchery voice, making the Sound of DNS idiosyncratic.
