Finnish melodic death stalwarts MORS PRINCIPIUM EST announce their long-awaited ninth studio album, Darkness Invisible. Officially signed to PERCEPTION, the latest imprint of Reigning Phoenix Music, the band will once again embrace listeners with razor-sharp riffing, sweeping orchestration, melancholic harmonies, and relentless rhythmic precision – topped by Ville Viljanen’s unmistakable vocals.
Viljanen comments: “Joining PERCEPTION marks a powerful new chapter for us. We’re proud to be part of a label family that houses so many legendary titans. With their support, we’re ready to unleash our most furious, blistering and ambitious work yet. The future burns bright, shrouded in “Darkness Invisible.””
“Throughout their career, MORS PRINCIPIUM EST have kept impressing me and the rest of the metal world with solid melodic death of the faster kind. Although they’ve never been the most active live band, they succeed in growing their following with each of their releases what underlines the masterfulness of their craft additionally…and in this case, ‘[Of] Death’ is really just the beginning. Welcome to PERCEPTION!” states label strategist Nils Wasko.
MPE are also not stingy with details above all: Darkness Invisible will finally be unleashed upon the world on September 26, 2025, and was once again self-recorded at Ansa Studio (Ulvila, Finland); Jens Bogren mixed and Tony Lindgren mastered the ten new tracks (plus CD / digital bonus song) at Örebro, Sweden’s Fascination Street Studios (AMORPHIS, SEPULTURA, KREATOR etc.). Alvaro Valverde Fernandez was hired to create artwork and layout.

Despite delivering MPE’s much-loved trademark elements, Darkness Invisible is not content to simply revisit old formulas, but it expands upon them: the arrangements are more cinematic than ever, layered with subtle electronic textures, ambient passages, and dynamic shifts that mirror the emotional weight carried within the lyrics – and the result is a work that feels both cathartic and devastating.
First single “Of Death,” also the opening track of their new record, a bone-shattering yet enormously melodic piece with a darkly majestic chorus, can be streamed here: https://mpe.rpm.link/ofdeathPR

About MORS PRINCIPIUM EST
Over the course of seven original studio albums, MORS PRICIPIUM EST refined their modern approach to melodic death metal again and again. Members came and gone, but their music remained untouched: razor-sharp riffing, sweeping orchestration, melancholic harmonies, and relentless rhythmic precision – topped by Ville Viljanen’s unmistakable vocals.
MORS PRINCIPIUM EST were founded in Pori in 1999 and are one of the longest serving Finnish melodic death metal bands. With frontman Viljanen being the most stable members, the present quintet survived several line-up changes before original members and guitarists Jori Haukio and Jarkko Kokko returned to MPE and already took part in recording their latest offering Liberate The Unborn Inhumanity [2022]. Also contributing to these refreshing re-recordings from their early years were former bassist Teemu Heinola and drummer Marko Tommila. A statement to honour the group’s history and to celebrate the freshly motivated line-up, which is now set to blast out their ninth album titled Darkness Invisible on September 26, 2025 through new label home PERCEPTION.
MORS PRINCIPIUM EST are:
Ville Viljanen | vocals
Jori Haukio | guitars, programming
Jarkko Kokko | guitars
Teemu Heinola | bass
Marko Tommila | drums
