SIGILO’s roots date back to 2014, when its sole creator first began exploring the bleak and uncompromising world of Black Metal. What began as an individual search for expression gradually developed through a number of early projects, each serving as a different stage in an ongoing process of experimentation, discovery, and personal transformation.
Among these projects, Mournkind became the most significant – a vessel through which raw emotion, darkness, and sonic exploration could collide without restraint. Over the following years, Mournkind became increasingly important in shaping this artistic vision. Yet beneath the surface, something new was beginning to take form.
In 2019, Mournkind was brought to an end, marking not a departure from its origins, but the beginning of a new chapter. From its ashes emerged SIGILO: a more focused and deliberate embodiment of the ideas, experiences, and emotions that had developed over the preceding years.
Where the earlier projects served as experiments and trials by fire, SIGILO became a process of refinement. The music turned increasingly inward – more introspective, solitary, and uncompromising – while remaining deeply rooted in the essence of Black Metal.
A major milestone came with SIGILO’s signing to Alma Mater Records, followed by the release of the split “Sermão” alongside Brazil’s Luxúria de Lillith. The release marked SIGILO’s emergence onto the wider Black Metal landscape, establishing a distinct identity while firmly acknowledging the genre’s foundations.
Now, after more than a decade of relentless creation, SIGILO presents its debut album, “Gloria ad Inferi”. Forged in solitude, shadow, and unwavering dedication, the album stands as both a culmination and a new beginning – a fierce, solitary declaration shaped by years of searching, transformation, and devotion to the black flame.
“Gloria ad Inferi” will be coming out on October 23 via Alma Mater Records. Physical formats can be pre-ordered HERE, while the digital release is available for pre-save at THIS LOCATION.
