I've been a fan of the weirdo "industrial" black metal bands for a while now (Blut Aus Nord, The Axis of Perdition etc.)
I liked Spektr's old stuff, but I think they came into their own with The Art to Disappear. Really riffy too.
I keep going back to this demo by Nuclear Winter. It's pre-Dead Congregation so you know it's going to be top notch death metal, really wish they would play the first track live one day.
