Literally anything by Prince Midnight. He plays black metal on a xylophone and a guitar supposedly made of the skeletal remains of his late uncle (Google it, it’s a fascinating rabbit hole lol). He calls his music “black metal” but to me it sounds more like black metal vocals mixed with The Doors, 80s style hardcore punk, and I guess eastern European folk music? A lot of the themes seem to be about Greek mythology. It’s a wild ride lol

Here’s a track to sample: Sword of Dardanos
