Faceless Killa
Most would actually classify them as Norwegian Black Metal....
Ok, first off, they're from Finland, not Norway.
Second, they aren't much like true Black Metal.
Third, what I meant by that was that their guitar riffing and soloing is power metal influenced. Children of Bodom are Death Metal, specifically Melodic or Melo-Death because of the influence of Progressive and Power metal on their keyboard and guitar style.
No one who actually knows black metal would even think of putting them in that category.
