Extreme or Melodic Black metal about TROLLS, not about anything else particular, Troll Metal can be ambient music also. Such bands can be looked upon websites for mass media purposes. Such as Mortiis(NOR), Trollmann Av Ildtoppberg(UK), Troll(NOR), and the Godfather of Troll Metal itself, Arckanum. More Troll Metal bands are coming into play soon.
Overly melodic 'extreme' metal. Characterized by strange band names, overly complex song titles, influence from classical music, and catchy choruses. Rhapsody, Bal-Saggoth, and Stormlord are all good examples of Troll Metal. See also Glory Metal.
Dude, this Troll Metal really sucks, but it's so catchy I can't stop listening to it.
