My friend introduced me to a new band that mixes melodic death metal/core with pop elements and actually succeeds. It sounds a lot to me like how the rock tracks from RWBY try to be, except they actually sound good to me. (Nothing against the RWBY soundtrack, but I always felt like something was missing from it, like it was incomplete or something.) It's called Amaranthe, and right now I'm listening to their album
The Nexus, which has a lot of good stuff.
I have a knack for finding metal bands with female vocalists. I also discovered Arven, Valora, and Delain. But, as for today, I'm just promoting this album.
