Bussanick recruited fellow Flourishing bandmate and bassist Eric Rizk and former http://www.progarchives.com/artist.asp?id=6459" rel="nofollow - Castevet drummer Ian Jacyszyn to complete Aeviterne's primary lineup, which released the two-track EP Sireless in 2018 via P2. The band took the next several years to carefully record and mix the songs for their debut, all of which were written before the release of Sireless. Aeviterne became a quartet with the addition of guitarist Samuel Smith (of http://www.progarchives.com/artist.asp?id=8874" rel="nofollow - Artificial Brain and http://www.progarchives.com/artist.asp?id=12000" rel="nofollow - Fawn Limbs ), and the band's first album, The Ailing Facade, saw the light of day in 2022, mixed and mastered by both Jacyszyn and http://www.progarchives.com/artist.asp?id=4865" rel="nofollow - Gorguts' Colin Marston and issued by Profound Lore Records. The record's concept deals with "turning inward to focus on the abyss of consciousness itself," namely: "the curse of sentience; the futility of productivity; the breakdown of consensus reality; humanity’s twin drives to propagate and destroy itself, locked in permanent perverse competition."
