Æolian is a melodic death metal band founded in Mallorca, Spain in 2016, featuring members with prior experience in the Balearic underground metal scene. Their debut album Silent Witness (2018) introduced an approach blending Gothenburg-influenced melodic death with threads of black metal and folk, and their follow-up The Negationist (2020) on Black Lion Records deepened that template while turning its lyrical focus entirely to environmental destruction and humanity's damage to the natural world. The band has drawn comparisons to Swedish melodic death progenitors while developing its own environmentally-conscious thematic identity. They signed to Black Lion Records ahead of The Negationist's release.
