Cor Scorpii play black metal that is somewhere between symphonic and progressive, with a considerable keyboard component. They have their own sound though; you don't feel like you're listening to a Dimmu Borgir clone, even if certain elements may seem reminiscent of bands like Arcturus or Borknagar. Keyboard and guitars occasionally go off on tasteful solos and tangents, and the band strike a good balance between melody and aggression. Their songwriting and delivery leaves no doubt that these are experienced musicians, in this case even used to playing in the same band. As a result _Attergangar_ feels like a good EP rather than a demo -- and indeed I wouldn't be surprised if Descent Productions decided to re-issue _Attergangar_ as an EP, as it certainly has enough quality to justify it and shouldn't remain in obscurity.
