Borknagar is a band from Bergen, Norway founded in 1995 by Øystein Garnes Brun. The band began as a black metal/viking metal band and quickly adopted a more progressive metal style after their first album. As such, the band's most known style would be that of progressive black metal, with most of their albums taking from this style. Borknagar's lyrics often deal with philosophy, paganism, nature, and the cosmos. Øystein Brun stated once that the name was inspired by a Scottish legend about a man who climbed Lochnagar, a mountain in Scotland.
