Hail True Metal

Hageshisa To, Kono Mune No Naka De Karamitsuita Shakunetsu No Yami - Dir En Grey

This is insane. The vocal range is amazing.

EDIT: Besides this song, Dir En Grey has no other Deathcore songs (that I know of).

Dir En Grey's a fairly strange (okay REALLY strange), somewhat interesting band, but they're certainly not a Deathcore band.

Merc, that band's instrumentals a insanely well done, but I don't really like the vocals that much.

Syllinger, the clean vocal style takes Root in the Visual Kei scene. You have to get used to it; it's an acquired taste.

Actually, it was the deep muffled growls that I didn't particularly like. The clean vocals were very well done.

That said, growling Japanese lyrics must be insanely tough. Aside from that nitpicking I really liked it; definitely playlist-worthy.

Oh, sorry about that. It's just most people don't like the visual kei-esque vocals. I agree with the point about the growls in Japanese.

Check out the song Vinushka by Dir En Grey. The growls that appear in that are less muffled than this, you may like it.
