Blackened screamo is a hybrid of skramz-era screamo and second‑wave black metal aesthetics. It blends the genre’s raw, emotionally charged vocals and desperate dynamic surges with tremolo‑picked guitar figures, blast beats, and an enveloping, cold atmosphere. Typical songs pivot between blistering speed and mournful, reverb‑drenched expanses. The harmony favors minor keys, dissonant clusters, and chromatic movement, while production often embraces intentional abrasion—lo‑fi edges, room bleed, and cavernous ambience—to intensify the sense of urgency and bleakness. Lyrically, blackened screamo carries screamo’s confessional, existential, and socially critical core, but frames it with black metal’s desolate, sometimes apocalyptic tone. The result is a cathartic, high‑intensity style that feels both immediate and vast.

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.

The new wave of speed metal is a 2010s revivalist movement that resurrects the breakneck tempos, razor‑edged riffing, and high‑energy songwriting of classic 1980s speed metal. It favors twin‑guitar harmonies, athletic rhythm sections, and soaring, clean vocals that deliver anthemic hooks. Unlike the harsher edge of thrash, this wave leans into melodicism and precision: galloping rhythms, tightly palm‑muted alternate‑picked riffs, and flamboyant guitar solos. Production tends to be crisp but analog‑minded, evoking vintage warmth while meeting modern loudness and clarity.

Deathcore is an extreme metal subgenre that fuses the riff language and vocal extremity of death metal with the breakdown‑centric impact of metalcore and its hardcore roots. Typical hallmarks include brutally palm‑muted and tremolo‑picked guitar riffs on low tunings, blast‑beat focused drumming with double‑kick barrages, and guttural growls, tunnel throats, and high shrieks. Songs commonly pivot into half‑time, groove‑heavy breakdowns designed for maximum physical impact. As a distinct movement, deathcore coalesced in the early 2000s and reached wider prominence in the mid‑2000s via internet platforms and relentless touring, even though earlier 1990s bands had already flirted with fusing death metal and hardcore elements.

Chaotic hardcore is an extreme strain of hardcore punk defined by rapid tempo shifts, dissonant riffing, and a deliberately unstable, “out of control” song structure. It typically combines hardcore’s speed and confrontation with the technical abruptness of mathcore and the abrasive noise of powerviolence/noise rock, creating short, explosive songs that often pivot without warning. Vocals are usually screamed, barked, or shrieked, and production often emphasizes raw impact: loud drums, jagged guitars, and a dense, clipped mix that makes the music feel physically overwhelming.

Hardcore (often called hardcore techno in its early form) is a fast, aggressive branch of electronic dance music characterized by heavily distorted, punchy 4/4 kick drums, tempos ranging from roughly 160 to well over 200 BPM, and a dark, high‑energy aesthetic. It emphasizes percussive drive over complex harmony, using clipped and saturated kick-bass sound design, sharp hi-hats, claps on the backbeat, and harsh synth stabs or screeches. Vocals, when present, are typically shouted hooks, sampled movie lines, or crowd chants processed with distortion and effects. Originating in the Netherlands in the early 1990s, the style quickly splintered into related scenes and subgenres such as gabber, happy hardcore, Frenchcore, terrorcore, speedcore, and later hardstyle. Its culture is closely associated with large-scale raves, specialized labels, and distinctive visual branding.
