Satanic Warmaster
One of the most famous Finnish black metal project (one-man band) from Lappeenranta, Etelä-Karjala, Finland, consisting of the sole musician "Werwolf" (real name Lauri Penttilä), since 1998. The lyrical themes are mostly covering topics about satanism, occult, and lycanthropia (werewolf). The band has received criticism due to accused NSBM-related lyrical themes.
The Chant of The Barbarian Wolves, One Shining Star, Black Metal Kommando are some of my favourite Satanic Warmaster songs. Werwolf must be a really great musician!
