Digipak reissue. Borknagar is the 1996 debut studio album by the Norwegian band of the same name. It is their only album to feature lyrics in the Norwegian language and their only album to feature Roger "Infernus" Tiegs on bass guitar. The album was recorded at Grieghallen Studios (frequented by other black metal bands such as Burzum, Emperor and Gorgoroth). The album features a more straightforward black/Viking metal approach (featuring heavy riffs, blasting tempos and an emphasis on harsh vocals) as opposed to the band's now trademark progressive/folk sound they would hint at on their next album, The Olden Domain.
