Founded in 2014 by Alexis and Alex Tetin in Maladzyechna, Sodomic Baptism explore themes of metaphysical evil and existential darkness through their death metal. Their discography, spanning from the "Black Fire Pandemonium" EP through 2025's "contra Christum," positions their brutality as a vehicle for philosophical confrontation with the abyss.

Stockholm's Sodomisery merge melodic death and black metal from the Swedish capital since 2017. Their transgression-misery portmanteau channels the suffering born of sin into compositions of darkly melodic capital-city extremity.

Soen formed in Stockholm in 2010 around drummer Martin Lopez and vocalist Joel Ekelof, with early attention also tied to bassist Steve Di Giorgio's involvement. Cognitive introduced a progressive metal band interested less in flash than in weight, atmosphere, and emotional control. Tellurian, Lykaia, Lotus, Imperial, and Memorial developed that approach into a distinct voice: spacious guitar figures, heavy but patient riffs, precise drumming, and Ekelof's calm, mournful vocal presence. Soen are often compared to Tool, Opeth, and Katatonia, but the band's catalog is more direct than that shorthand suggests, using progressive structure to intensify songs about power, loss, conflict, and moral unease. The rhythm section is sophisticated, yet the arrangements usually preserve a clear melodic arc, which makes the music accessible without flattening its complexity. Their metal identity comes from the riffs, drum force, and dark harmonic language, while the progressive side comes through pacing and restraint. Soen's best songs feel sculpted rather than jammed, with each heavy section arriving after a controlled buildup and emotional turn.
