Corrupted is a mysterious Japanese doom metal band, formed in 1994. Immensely down-tuned guitar and crushingly slow bass are shrouded under deep layers of feedback. They are rightly hailed as one of the heaviest and darkest doom metal bands of all time. This record isn't your standard doom fare. The title-less tracks are to be played at either standard vinyl speed. Therefore, and at the band's request, no samples or download code. This 12" pressing of Felicific Algorithim is also accompanied by a foldout poster.
