I think it’s useless, and a waste of time, to make a full introduction on Satyricon. This Norwegian duo (Frost and Satyr Wongraven) is Elite in different aspects. I still consider their earliest works, and their debut full length Dark Medieval Times more specifically, as CULT, but since they turned into a rather Post-Black oriented form of Musical Extremism, they reached a wider audience; but still they deserve it.
