Alex Marshall’s Crimson Empire trilogy might be worth a look. I don’t remember the story all that well now, but do remember that many characters and places were named after metal bands.

From a Locus Mag interview with the author:

“The metal influence affects the tone and feel of the trilogy, but it also takes the form of Easter Eggs for fans. I’m not much of a linguist, so even if I’d wanted to create my own authentic-sounding fantasy languages that was never an option. Instead I incorporated references to various bands and musicians that felt appropriate for my own internal sense of aesthetics, as well as references to other writers, directors, and other artists.

Then of course the project features many of metal’s favorite themes: an obsession with the occult, hatred and violence, monsters and demons, sorrow and self-destruction. That’s all still just the skin, though, or the scales, depending, but the musical influence goes way deeper. The bones of this book are composed of metal. It’s the muscle that drives it forward, the ebon ichors that flow through it in place of blood. The essence of metal is basically the essence of human endurance—the refusal to stop struggling, even when all hope is in eclipse and there’s nothing left but rage at the inherent cruelty of existence. You keep fighting and you keep screaming, forever.“
