Nifelheim is one of the only bands in Black Metal that has continued to produce a consistent style of metal in a 10 year history. With each of their albums improving in production, Servants of Darkness is just one step farther down into their world of evil. I would recommend this album, as well as any of their albums. If you want to listen to Black Metal in the vein of Bathory, Venom, Hellhammer, and Sodom, and have it rock faster, heavier, and more evil that any of the above mentioned, then buy Servants of Darkness.
