De Profundis is to black metal what Opeth is to death metal. Although Opeth has shied away from their death metal roots on more recent releases, De Profundis still waves the black metal flag proud on "The Emptiness Within". The album features some interesting jazz signatures mixed with classic black metal, giving the album a multi-dimensional attack. Songs such as "Silent Gods" and "This Wretched Plague" offer a perfect example of the bands brand of prog black metal. Fans of Opeth and prog rock should definitely check this band out. Pretty solid album throughout.
