GRIMNIS Unleash Relentless Blackened Deathcore with New Single ‘Key of Bones’


German blackened deathcore outfit GRIMNIS have unleashed their latest single, Key of Bones, accompanied by an official music video that premiered on July 5, 2025. This release marks the third single from their highly anticipated debut album, The Path ov the Flame, set to drop on August 9, 2025.

Key of Bones opens with eerie, discordant melodies before plunging into downtuned riff assaults, relentless blast beats, and guttural demonic growls. Each breakdown hits like a seismic event, while the atmospheric layers give the track depth beyond sheer aggression. Themes of decay, mortality, and occult mysticism permeate every second, drawing listeners into a ritual of brutal beauty.

The production is stark and thunderous—designed to almost suffocate under its own weight, yet retains clarity within the chaos. Fans of Lorna Shore, Vulvodynia, and Enterprise Earth will find Key of Bones both familiar in its brutality and fresh in its atmosphere.

With this release, GRIMNIS reaffirm their position at the forefront of Germany’s blackened deathcore scene—unrelenting, cinematic, and imbued with dark mysticism.

Key of Bones is available now on all major streaming platforms. Enter the crypt.
