For however much black metal continues to be commercialised and crassly made into a marketable parody of itself, there exist true aesthetics terrorists with such fanatic ideology and frightening vision to keep the genre - grounded - in the dirt, in the grime, of the soul. MERRIMACK is one such band. The French horde have provocatively pursued its (ir)religious inspiration its inception in 1994. “Grey Rigorism”, its latest offering, is a testament to true underground spirit being suffused with startling professionalism. Hellfire and focus - damnation awaits.
