Courtesy of weed and death, Rigorous Institution, a band of churls and deranged actors, joined together in the rainy gloom of Portland's terroristic streets, Year of Our Lord 2018, releasing their first demo that year. In 2019 they oppressed the world with their EPs 'Penitent', and 'Coming of the Terror' and in 2022 their full length work 'Cainsmarsh' further sharpened the assassin's dagger of their sound, full of menace and dark premonitions. Music for a civilization in decay.
