Yes. I retain my tr00ness even in power metal, and how do I do this? With a band known as Finist. They are ... I suppose blackened power metal with get this ... National Socialist lyrics.
Led by Saturious of bands such as Nokturnal Mortum and Aryan Terrorism, we have great power metal led by great crunchy guitar riffs, appropriate use of keyboards, good harsh black metal typical vocals, and really prideful and passionate clean vocals.
If you are not bothered by themes of Aryan pride and what not then this band is a good one to check out when you are sick of the typical power metal band, especially vocally.
