I don't have many information about Ev of Isis, I only know that it is a collaboration between Stockholm's Josefin Hinders (drummer in Forest) and San Diego's Amanda Schoepflin (Cathedral X). "Dark Ambition" is their first release and it's a seventeen minutes tape released by Belaten. The six tracks sound like a nightmarish dream where reversed sounds are mixed to filtered screams, dark ambient bass drones and hisses. Vocals are reversed, slowed down and treated, just to make them sound like regurgitated from hell. Sometimes the tracks sound like a sort of mix of the 80s 4AD sound and the early Cold Meat Industry sound: something that has some melodies, some catchy insert but also a level of illness which could you make remind of Aghast. Maybe they used a little too much the reversed drums sound which after a while is like sucking everything else, but the overall effect is good.
