Great literature has always been a source of inspiration for heavy metal bands. J.R.R. Tolkien for Blind Guardian, H.P. Lovecraft for Cradle of Filth, The Holy Bible for Stryper and now The IKEA Catalog for Nanowar Of Steel. Valhalleluja is Nanowar's personal take on modern days Norse Mythology, where alongside Odin, Thor and Loki also the greatest Swedish heroes of our age - Beddinge, Kivik and Knopparp - are sitting in Valhalla.
