瑞典祭祀黑氛团Ulf Söderberg乃是CMI旗下Sephiroth的分支,至今出了三张专集。Ulf Söderberg对神话、宗教仪式、庙宇遗迹等考古文化有着浓厚的兴趣。
Sephiroth was created in the year 1990 by Ulf Söderberg, through a genuine and burning interest for myths, rituals, and enigmatic monuments and places erected by mankind itself. Influenced by Graeme Revell, Lustmord and Nurse With Wound, Sephiroth relate stories about the inexorable and destructive power of Time, mankind's futile attempts of resistance, and the sunken cities, fallen towers, and overgrown ruins that this has resulted in. Dark eerie soundscapes and ritualistic drums are combined with own field recordings from places like Cairo, Iceland and gloomy Nordic forests.
