Disharmonium – Nahal (Debemur Morti Productions) is the sixteenth full-length release from Blut Aus Nord, the enigmatic French avant-garde black metal band that have now existed for thirty years. Following on from last year’s Disharmonium – Undreamable Abysses, this new record also draws inspiration from H.P Lovecraft and is claimed by its accompanying press release to be “womb-like, detail-rich, disturbed and transformative”.
