Abyssal seamlessly ties together unique musical ideas into a cohesive whole. Distinct and non-formulaic, yet still unquestionably Abyssal, G.D.C. clearly has a grasp on what the band's true essence is (which I don't). Somehow the unassuming lyrical theme is made to fit the music as well.
Ellorsith pairs very nicely with Abyssal both in sound and the dark emotions in musical form, with a fittingly twisted theme. A very focused split, no boring parts on either band's side.
Favorite track: Abyssal - Sepulchorporeal (Ipatiev I).
