Sons of Balaur is a black metal act originating from the United Kingdom in 2015 as a fictional band from within the 'Realm of the Damned' graphic novel universe, before being brought to life as a performing group. Signed to Season of Mist, the band released their debut album Tenebris Deos in October 2016, presenting raw, orthodox black metal with a backstory constructed around the mythology of the graphic novel series. The project blurs the line between art concept and genuine band with deliberate intent, and the music itself — guitar-driven and tradition-minded — requires no narrative scaffolding to stand on its own terms.

Sons of Cain forge doom and sludge metal from Aalborg in northern Jutland, channeling biblical fratricidal themes through crushing compositions. Active since 2018, they bring the weight of the first murder to the North Jutland underground.

Sons of Cult play heavy metal and hard rock from Palma in the Balearic Islands, channeling classic metal energy from the Mallorcan capital. Formed in 2023, they bring cultish devotion to traditional metal on the Mediterranean island.

Sons of Decay blast through black, thrash, and death metal from Donostia-San Sebastian, combining three extreme genres from the Basque coastline. Formed in 2020, they bring triple-pronged aggression to the Basque underground.

Belgian metal-punk five-piece from Herenthout active for nearly two decades, blending old-school heavy metal mayhem with straightforward punk mischief across releases like "Judge Hammer" and "Large Hadron Collider Spider." Known for exhilarating riffs and full-throttle stage antics, they embody a distinctly Belgian fusion of metal and punk energy.

Vladimir's Sons of Northern Mist merge melodic death and power metal from the Golden Ring city since 2013. Their boreal heritage name and origins in one of medieval Russia's most important principalities channel northern identity into ambitious, melody-driven compositions.

Sons of Seasons formed in Aachen, Germany in 2007, organized around Kamelot keyboardist Oliver Palotai, who wrote and produced the band's material and recruited vocalist Henning Basse alongside bassist Jürgen Steinmetz and drummer Daniel Schild. Their debut Gods of Vermin (2009) introduced a dramatic symphonic power metal sound with progressive touches, and Magnisphyricon (2011) expanded the band's compositional ambition further. The project draws on the same European tradition as Kamelot while emphasizing a darker, more orchestral palette. Sons of Seasons have remained a part-time vehicle for Palotai's songwriting outside his primary band obligations.

Sons of Sorrow deliver melodic deathcore from the eastern Finnish town of Kontiolahti, combining Scandinavian melodeath with modern breakdowns. Active since 2013, they bring sorrowful intensity to the North Karelia scene.

Sons of the Beast deliver thrash metal from Madrid, channeling aggressive velocity with their Iron Maiden-evoking name. Active since 2012, they bring beastly intensity to the Spanish capital's thrash scene.
