(not Maiden

)
Anyways, I bought these guy's "Dark Assult" album a number of years ago and never really got into it. I was expecting more vocals from Kai Hansen, I suppose. Piet Selek's voice is kind of gruff, wasn't really into that at the time. Not to mention that some of their double-kicks seemed out of place.
...That is until I decided to test out my new speakers with them! Maybe it's the years of age, or maybe it's even the new speakers, but these guys are actually pretty sweet! (Even if I do like the Kai Hansen voiced stuff better).
Just thought I'd bring them up, because when it comes to power metal they actually kick some serious ass! I //was// considering bringing them up for Prog-Metal inclusion, since they're a concept band with some pretty freaky, sci-fi lyrics that any prog-head into that kind of thing could enjoy. HOWEVER, after a couple listenings, it's fairly clear that they're just power-metal with a concept... good power-metal with a concept.
So, after seeing no discussions about them, what do you think of them? (As a power metal band, not in a progressive scope).
