Merrimack’s Grey Rigorism, issued on Moribund Records, is an uncompromising slab of Black Metal built from icy tremolo riffs, guttural snarls and oppressive, lo‑fi production. It favors muscle and atmosphere over ornamentation, rooted in a raw, mid‑tempo attack that suits listeners of the genre’s darker, heavier strains. It has 948 listens from 22 users, underlining steady underground traction.
