He has not the power of a Secret of The Runes, not the elegance of a Vovin or Theli, but it has its own personality.
To be honest, I was a little confused after the first listen: sounds very (too) rich, fairly complex music (incredible bass lines on some tracks), many sounds typed 70 (influences from Black Sabbath Led Zep ', Pink Floyd) and virtual disappearance of Metal ...
In short, good advice, listen before you buy.
If you do not know Therion but you are lovers of Rock, it may be a good album to gently immerse yourself in this universe.
If you swear by Therion before ... we'll have to open your mind.
