Retro metal is a 2000s-era revival of the riff-first, analog-warm heavy sounds associated with 1970s/early‑1980s hard rock and classic metal. Its bands deliberately echo the era’s fuzzy guitar tones, blues-rooted riffs, occult/psychedelic aesthetics, and live-in-the-room production choices. Critics used the label for groups that drew heavily from Black Sabbath, Pentagram, Deep Purple, and the NWOBHM palette, often blurring lines with stoner/doom and psychedelic rock. The result is mid‑tempo grooves, stacked twin‑guitar harmonies, vintage keyboards or organs, and vocals that range from soulful grit to nasally occult croon.

Psychedelic doom is a fusion of doom metal’s slow, crushing weight with the heady textures and exploratory spirit of psychedelic and space rock. It emphasizes down-tuned, fuzz-laden guitars, hypnotic repetition, and long-form compositions that drift between ominous heaviness and trance-like, kosmische atmospheres. Production often favors analog warmth, tape-like saturation, spring reverb, and echo, while vocals are typically distant, reverb-soaked, and occult- or cosmos-themed. The result is music that feels both monolithic and mind-expanding: lumbering riffs, ritualistic grooves, and hallucinatory effects that evoke horror cinema, esoteric mysticism, and deep space.

Stoner metal is a heavy, riff-centered offshoot of doom metal that fuses the low-and-slow weight of early Sabbath with the hazy psychedelia and fuzz-drenched tones of 1970s hard rock. It emphasizes down-tuned guitars, thick midrange, and hypnotic, groove-forward drumming, often evoking a desert-heat mirage of sustained riffs and feedback. Compared to stoner rock, stoner metal leans darker and heavier, with a doomier pulse, longer song structures, and an almost trance-like fixation on repetition. Lyrics frequently explore cosmic wanderlust, occult imagery, apocalyptic visions, and cannabis counterculture, while production tends to favor warm, analog saturation and room-heavy drum sounds.

Stoner rock is a heavy, riff‑centric style that blends the weight and doom of early heavy metal with the groove and expansive jams of late‑60s/70s psychedelic and acid rock. It is marked by fuzz‑drenched, down‑tuned guitars, thick bass tones, and relaxed but powerful mid‑tempo grooves. Songs often emphasize hypnotic, repetitive riffs; extended instrumental passages; and a warm, vintage analog sound. Vocals tend to be laid‑back or gritty rather than operatic, and lyrical themes commonly explore the desert, space, altered states, mythology, and countercultural imagery. The overall vibe is earthy and immersive—equal parts head‑nodding groove, psychedelic haze, and Sabbath‑born heaviness.

Sludge metal is a hybrid of doom metal’s slow, downtuned weight and hardcore punk’s raw aggression. It emphasizes thick, overdriven guitar tones, throttling bass, and drums that lurch between trudging slow-motion grooves and ragged mid‑tempo blasts. Vocals are typically screamed, barked, or anguished, often buried slightly in the mix to feel abrasive and cathartic. The style took shape in the late 1980s United States—particularly the Pacific Northwest and the American South—where bands fused Sabbath‑like doom riffs with the DIY harshness of hardcore and the scabrous textures of noise rock. Lyrical themes commonly explore addiction, despair, social decay, and Southern Gothic imagery, delivered with an intentionally gritty, unvarnished production aesthetic.

Doom metal is a heavy metal subgenre defined by slow to mid-tempo grooves, down-tuned, highly distorted guitars, and an atmosphere of dread, melancholy, and weight. It emphasizes ominous, minor-key riffs and sustained tones over speed or virtuosity, creating a crushing sense of space and inevitability. Vocals range from plaintive and theatrical (epic/traditional doom) to anguished wails or harsh growls (death-doom), and lyrics often explore themes of suffering, mortality, the occult, apocalyptic visions, and existential despair. Song structures are typically riff-centric and long-form, with repetition and gradual dynamic shifts producing a hypnotic, ritualistic feel.
