Hmmm, Eluveitie, Black Kirin, Bathory, apocalyptica maybe? That should cover some range for you to try different things (although they are not obscure either). Demetori is really cool imo; but it's doujin so """amateurish""", and specifically around Touhou fanbase.

For rock... 珂拉琪 Collage, there's a Light, Toe, DSPS, MASS OF FERMENTING DREGS, a picture of her, Itsue...
Those are more post rock, experimental, shoegaze, math rock though

Bathory! U dont move me i dont give a fck!
