Ikuisen Tulen Kammiossa is a very strong debut if you like old Gorgoroth (without outright seething coldness, as Ikuisen Tulen Kammiossa is much warmer and earthier), Taake, Horna or Calvarium. The album is a perfect example of how not to hide behind the conviction and try scoring points on pure genre tenets. But, then, I guess you need quality musicianship, attention to detail in the studio and ability to play your instruments, something not every underground black metal possesses. Sacrificium Carmen definitely belong with the underground Finnish black metal, there is no shine or artificial polish here, yet the album is definitely worth purchasing.
