Black Metal Art LoRA — SDXL Style LoRA for Black Metal Visual Art

A LoRA fine-tune of SDXL 1.0 trained on black metal album covers, band logos, and zine art. Generates high-contrast dark art in the visual language of black metal: fog-drenched forests, burning churches, corpse paint portraits, illegible spiky logos, frozen mountain landscapes, and occult imagery — the raw, monochrome aesthetic from the early Norwegian scene through modern atmospheric and DSBM.

Trigger word: black-metal-art

Logos & Typography

Black metal logos are intentionally illegible — garbled, spiky text output is a feature, not a bug. Higher LoRA scales (0.7–0.8) produce more authentic logo aesthetics.

Usage

With Diffusers

python
import torch
from diffusers import StableDiffusionXLPipeline

pipe = StableDiffusionXLPipeline.from_pretrained(
    "stabilityai/stable-diffusion-xl-base-1.0",
    torch_dtype=torch.float16,
    variant="fp16",
)
pipe.load_lora_weights("cahlen/black-metal-art-sdxl-lora")
pipe.set_adapters(["default_0"], adapter_weights=[0.7])
pipe.to("cuda")

image = pipe(
    prompt="black-metal-art, dark forest, fog, dead trees, high contrast, monochrome",
    negative_prompt="blurry, photorealistic, photo, smooth gradients, 3d render, watermark, clean, modern, digital",
    width=1024,
    height=1024,
    num_inference_steps=30,
    guidance_scale=7.5,
).images[0]

image.save("black_metal_art.png")

With ComfyUI / A1111

Load pytorch_lora_weights.safetensors as a standard SDXL LoRA. Use trigger word black-metal-art in your prompt.

LoRA Scale Guide

0.5Moderate style influenceSubtle dark atmosphere, blending with other styles
0.6Strong style, good detailLandscapes, portraits, album cover compositions
0.7Full black metal aestheticForests, churches, corpse paint — the default sweet spot
0.8Very strong, maximum styleLogos, abstract dark imagery, maximum raw aesthetic

Text & Logo Generation

Unlike most LoRAs, garbled text is welcome with this model. Black metal band logos are famously illegible — the spiky, branch-like letterforms that SDXL generates naturally match the genre aesthetic. For logo generation, use higher LoRA scales (0.7–0.8) and prompts like:

  • —black-metal-art, illegible spiky band logo, branches and thorns
  • —black-metal-art, band logo, flames, inverted cross, black background

Prompt Tips

  • —Always start with the trigger word: black-metal-art
  • —Landscape prompts work great: forests, mountains, frozen lakes, graveyards, ruins
  • —Monochrome keywords reinforce the style: high contrast, monochrome, black and white
  • —Atmospheric keywords: fog, mist, bleak, desolation, frozen, winter
  • —Best subjects: dark forests, burning churches, corpse paint, mountains, wolves, ravens, skulls, occult symbols, band logos
  • —Album cover format: Use 1024x1024 square resolution

Why SDXL over FLUX

SDXL 1.0 (3.5B parameters) was chosen over FLUX (12B+) because FLUX's strong photorealistic prior overwhelms rank-32 style LoRAs. SDXL's smaller parameter count is more amenable to specialized art styles at practical LoRA ranks.

Style Reference

This LoRA captures the visual language of black metal art:

  • —High-contrast monochrome — dark, raw, uncompromising
  • —Norwegian black metal scene — the iconic aesthetic of Mayhem, Burzum, Darkthrone, Emperor
  • —Frozen landscapes — snow-covered forests, mountains, desolate winter scenes
  • —Burning churches — the infamous visual motif of early Norwegian black metal
  • —Corpse paint — the theatrical black and white face paint
  • —Illegible logos — spiky, branch-like letterforms, intentionally unreadable
  • —Occult imagery — pentagrams, inverted crosses, goat heads, ritual scenes
  • —Album cover compositions — wolves, ravens, skulls, ancient ruins

This LoRA inherits the CreativeML OpenRAIL-M license from the SDXL base model.
