This band needs no introduction: Nightrage has left its marks in the Scandinavian metal scene and is a force to be reckoned with that stands for quality. Over the years, and releases mastermind Marios Iliopoulos & Co. have discovered a general, persistent sound that brings together the best moments of melodic death and harsh thrash metal with progressive tendencies and reflected guitar work. On their last album Wearing a Martyr's Crown Nightrage reminded of the overwhelming clout of the 'traditional' Gothenburg-style. With Insidious the band approach widens again, without restraining acrimony or vehemence. Instead, the quintet changed the context of its challenging playground.
