The name really speaks for itself. I can't tell you much about the band since I never listened to them earlier. However, this album blew me away completely. In fact, I now have their entire discography and I'm going through it with a sick and twisted grin on my face.
Now, since I'm more delighted than competent to discuss their music at the moment, I'm gonna quote a friend: "They're always changing, but dissonance and fucked-up melodies were always present. They were always miles in front of everybody else, breaking the barrier of that simple black metal aesthetics."
