I always hear about PIRATE metal, but what about NINJA metal? C'mon! I wanna hear about ninja metal!
Not too fond of it myself but I like Amon Amarth and Enslaved to fill my Viking niche.
Tyr Amon Amarth (if you count them as viking metal)
Hey I added you Erik I'm a merciless fan of Bathory and their Viking albums. I also like Moonsorrow, Enslaved, Ensiferum (I think you recommended them to me), Falkenbach and Vintersorg. FYI Amon Amarth aren't Viking they're Melodic Death Metal but thats cool. I didn't even know that Pirate Metal was a genre. Towards the Pantheon
