It's Fucking Bal-Sagoth dude! They give new meaning to writing concept albums. The idea for the band name is taken from the short story "The Gods of Bal-Sagoth" written by Robert E. Howard, who is better known for creating Conan the Barbarian. That song is from the album titled Starfire Burning Upon The Ice-Veiled Throne of Ultima Thule. The album uses some of the theme music from the 1980s movie Conan the Barbarian. I recommend giving them a listen!
