Hammerheart is an album with an epic sound to it. Some would classify it as Folk- or Viking-Metal. Quorthon’s voice is kind of a cross between screaming and singing; possibly wailing at some points. Although “Blood, Fire, Death” is considered by many to be the first “Viking Metal” album, I feel that “Hammerheart” is the first FULL album that is Viking Metal. “Blood, Fire, Death” is mostly speed metal with a Viking theme. If you crave an epic folk metal sound, then this album is for you!
