Cavernous death metal is a murky, reverb-drenched strain of old-school death metal that foregrounds claustrophobic atmosphere over clinical precision. Hallmarks include extremely downtuned guitars, tremolo-picked and chromatic riffing, lurching doom-laden passages, and very deep, often indecipherable guttural vocals. Production aesthetics are central: drums are thunderous yet blurred, guitars and bass form a monolithic wall of low-end, and large-room or plate reverbs smear the mix to evoke the feeling of sound emanating from a subterranean chamber. Rather than bright, high-fidelity tones, the style prefers darkness, distance, and density—suggesting sinister space, decay, and ancient dread. Compositionally it draws on early 1990s death and death-doom blueprints, but the 2010s revival codified the "cavernous" sound as a distinct aesthetic, emphasizing mood, negative space, and oppressive resonance as much as riffcraft.

Experimental black metal is a boundary-pushing branch of black metal that blends the genre’s core harshness with unconventional composition, timbres, and aesthetics. It commonly replaces or augments traditional tremolo-picked riffs and blast beats with dissonant harmonies, odd meters, through-composed forms, and unusual instrumentation (synths, saxophone, strings, prepared piano, electronics, noise). Vocals range from classic shrieks to chants, spoken word, harmonized clean passages, and processed textures. Production can be deliberately lo‑fi and abrasive or hi‑fi and cinematic, but it is typically textural: layers of feedback, drones, and spectral effects are used as musical material. Lyrically, it gravitates toward esoteric philosophy, surrealism, urban decay, cosmic dread, and psychological or spiritual dislocation, prioritizing atmosphere and conceptual depth over orthodoxy.

Cosmic death metal is a branch of death metal that fuses technical and progressive riffcraft with space‑oriented atmospheres and science‑fiction thematics. Musically, it combines the heft and speed of classic death metal with expansive, reverb‑drenched leads, layered synths or guitar textures evocative of deep space, and frequent metric and harmonic shifts. Lyrically, it explores cosmology, extraterrestrial life, cosmic horror, and metaphysical themes. The result is a sound that feels both crushingly physical and vast, often alternating between precision blast‑beat assaults and weightless, ambient or psychedelic passages that suggest starfields and voids.
