Korean Songs (Non-Kpop)

Lets start a thread where we can share some good Music that are non K-POP because most of the other threads usually and mostly contains POP music and I love korean music but I'm not that into kpop so This is a thread for sharing Ballads/Indie/UnderratedSingles/Jazz/Folk/Alt. Rock etc. 

Let's Begin! :)

Some screamo/post-hardcore (although I don't like these genres, those guys seem nice)
I would like to find some korean metal, like death metal or so, but I didn't find anything :( only k-pop exist in Korea? :|
