Aethereus is a progressive technical death metal band hailing from the soggy Pacific Northwest city of Tacoma, Washington. First introducing their visceral brand of tech death to the world with their 2015 EP, the band merges dizzying technicality with ethereal melodies and dissonant aggression, a combination that has only grown stronger with each release. Blending the technical skill of modern death metal with the raw energy and atmosphere of its forbears, Aethereus aims to create music that is sonically powerful and emotionally impactful.

In the wake 2020’s pandemic-induced tour cancellations, the band decided to make lemonade and poured every ounce of energy, anxiety, and stress into finishing their monstrous follow-up album, “Leiden.” Mixed and mastered by renowned engineer Christian Donaldson (Cryptopsy), "Leiden" was completed and released January 14th, 2022 on The Artisan Era Records to glowing reviews.
