Aeternus
Aeternus is a Black/ Death/ Dark band from Bergen, Norway. It was formed in 1993 as an idea of Ronny Hovland, calling himself Ares, and Erik Heggernes, aka Vrolok. Later in 1996 Nicola Trier, aka Morrigan, joined the duo as a bass player, forming the core trio that created the important first two albums of the band. Morrigan also created the logo picture of ravens and axes that still exists as one of the band's trademarks.
Usage examples of "aeternus".
I also listen to Ataraxia, Mantra, and Sopor Aeternus, and dark ambient stuff like Endura.
Sopor Aeternus brought back tender memories of listening with Sheena as well as creating an appropriately heartaching mood.
