It?s been five years since the previous Keep of Kalessin album, and the band has gone through some odd times. But the Norwegian progressive black metal trio have finally returned with Epistemology, and they?re not holding back. They?ve refined their sound, rediscovered themselves and as a result created an album that hits the listener like a freight train of blast beats, chants and an orchestral section accompanied by frontman ?Obsidian Claw? Arnt?s trademark brand of ridiculous guitar playing. With all the epicness of power metal and speed of black metal, Epistemology is an invigorating and overwhelming tour de force.
