Death metal is an extreme subgenre of heavy metal defined by heavily distorted, low‑tuned guitars, rapid and complex riffing, blast beat drumming, and harsh guttural vocals. Its harmonic language favors chromaticism, dissonance, and tremolo-picked lines that create an ominous, abrasive atmosphere. Lyrically, death metal often explores dark or transgressive themes—mortality, mythology, anti-religion, psychological horror, and the macabre—sometimes with philosophical or social commentary. Production ranges from raw and cavernous to hyper-precise and technical, reflecting the genre’s many regional scenes and substyles. From the mid‑1980s Florida scene (Tampa) and parallel developments in the US, UK, and Sweden, death metal evolved into numerous branches including brutal death metal, technical death metal, melodic death metal, and death‑doom, each emphasizing different aspects of speed, complexity, melody, or heaviness.

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.

Drone is a minimalist music genre defined by sustained tones, long durations, and extremely gradual change. Harmony is often static or centered on a single fundamental with subtle overtone shifts, while rhythm tends toward stasis or very slow pulses. Sound sources range from acoustic instruments (e.g., strings, organ, bagpipes, shruti box, tambura) to electronics (sine waves, oscillators, feedback, tape loops, and later digital synthesis and processing). Many composers favor just intonation or other alternative tuning systems to emphasize beating patterns, psychoacoustic effects, and the internal life of sound. Although drone as a sonic principle is ancient and global, the modern experimental genre cohered in the 1960s through the New York minimalists and related avant‑garde circles, then spread into ambient, experimental, and heavy music scenes. The focus is less on melody and more on timbre, resonance, and the phenomenology of listening.

Experimental music is an umbrella term for practices that prioritize exploration, process, and discovery over adherence to established genre norms. It embraces new sound sources, nonstandard tuning systems, indeterminacy and chance operations, graphic and open-form scores, extended techniques, and technology-led sound design (tape, electronics, computers, and live processing). Rather than a single style, it is a methodology and ethos: testing hypotheses about sound, structure, and performance, often blurring boundaries between composition, improvisation, sound art, and performance art. Listeners can expect unfamiliar timbres, unusual forms, and an emphasis on how music is made as much as the resulting sound.

Lo-fi is a music aesthetic and genre defined by an embrace of audible imperfections—tape hiss, clipping, room noise, distorted transients, and uneven performance—that would be treated as errors in high-fidelity recording. Emerging from the DIY ethos of American indie and punk scenes, lo-fi turns budget constraints and home-recording limitations into a signature sound. Songs are often intimate, direct, and unvarnished, prioritizing immediacy and personality over polish. Typical lo-fi recordings use 4-track cassette or similarly modest setups, simple chord progressions, and understated vocals, spanning rock, folk, pop, and experimental approaches while retaining a homemade warmth and nostalgic patina.

Metal (often used to mean heavy metal in its broad, umbrella sense) is a loud, guitar-driven style of rock defined by high-gain distortion, emphatic and often martial rhythms, and a dense, powerful low end. It foregrounds riff-based songwriting, dramatic dynamics, virtuosic guitar solos, and commanding vocals that range from melodic wails to aggressive snarls and growls. Harmonically, metal favors minor modes, modal color (Aeolian, Phrygian), chromaticism, and tritone-inflected tension, while thematically it explores power, mythology, the occult, social critique, fantasy, and existential subjects. While adjacent to hard rock, metal typically pushes amplification, distortion, precision, and thematic intensity further, forming a foundation for many specialized subgenres.

Old school death metal (OSDM) is the formative, raw strain of death metal that took shape in the mid-to-late 1980s. It emphasizes downtuned, palm-muted riffing, tremolo-picked lines, and thunderous drums that shift between blast beats, skank beats, and mid-tempo stomps. Vocals are guttural and cavernous, projecting themes of mortality, horror, occultism, and decay. Production is intentionally unvarnished: guitars are thick and abrasive, drums are natural and roomy, and mixes privilege heaviness and atmosphere over precision. US bands typically favored tight, chug-heavy riff chains and chromatic menace, while the Swedish branch popularized the infamous “buzzsaw” guitar tone driven by the Boss HM-2 pedal. Song structures often unfold as riff-suites rather than strict verse–chorus forms, creating an inexorable, subterranean momentum.

Industrial black metal is a hybrid style that fuses the icy tremolo-picked guitars, blast beats, and shrieked vocals of black metal with the mechanized rhythms, electronics, and abrasive textures of industrial and post‑industrial music. Typical signatures include programmed or heavily processed drums, distorted or bit-crushed synthesizers, samples and noise layers, and cold, machine-like grooves placed beneath or around black metal riffing. The result emphasizes harsh timbres, dystopian atmospheres, and a mechanistic precision that replaces (or pointedly contrasts) the lo‑fi, organic rawness associated with early black metal. Lyrically and aesthetically, the style often explores themes of technology, urban decay, anti-humanism, cosmic nihilism, and science-fiction horror, frequently adopting cyberpunk or post-apocalyptic imagery and using visual design borrowed from industrial culture.
