Answer:
finntroll is a folk metal band from helsinki , finland .they combine elements of black metal and folk metal .finntroll 's lyrics are mostly in swedish , the only exception being the song `` madon laulu '' on `` visor om slutet '' .finntroll 's original singer , katla , decided to use swedish over finnish since he was part of a swedish-speaking minority in finland and the sound of the language seemed to better suit the band 's `` trollish '' outfit .despite several vocalist changes , this tradition has continued .according to bandmembers vreth and skrymer , they took their name from an old finnish legend where swedish priests coming to finland had an encounter with a wild-looking man who killed most of their party .the survivors came back bearing the tale of the finn-troll .finntroll 's lyrics mainly deal with legends and tales revolving around the fictional troll-king `` rivfader '' and the trolls fighting against the christians who entered their lands and spread their beliefs .a recurring theme is the story of two priests named `` aamund '' and `` kettil '' .the first three full-length albums feature a rather short but fierce song about the two men who constantly get themselves into trouble with the trolls , only to get beaten up and mutilated over and over again by the wrathful followers of rivfader .to date , the band 's discography includes six full-length albums , a live album and two eps .their newest studio album blodsvept was released on march 22 , 2013 .in 2014 , the band released the live album `` natten med de levande finntroll '' -lrb- `` night of the living finntroll '' -rrb- .
