Seoul-based South Korean sludge metal miserists Gawthrop join Sentient Ruin for "Deterioration", a glorious torment and misery-f***ed 12" vinyl compilation of the band's first two incredible demo tapes (2019's "Demo" and 2022's "Jumbo"). A wretched amplifier worshipping monstrosity of complete antihuman heaviness, the glorious release channels the hate-drenched and bottom-caving megaton DOOM of legends like Corrupted, Meth Drinker, Nootgrush, Grief and Thorr's Hammer into six colossal slabs of pure earth-shaking, downtuned slow-crawling sonic torment that will stomp, crush and flatten the listener to death.
