Thall is a hyper-percussive, ultra–low-tuned offshoot of djent and progressive metal popularized by Sweden’s Vildhjarta. The style emphasizes tightly gated, staccato down‑picking; dissonant chord voicings; and lurching, polymetric grooves that drop into sudden rests and accents. Characteristic techniques include rapid release bends, stark contrasts between pitch‑shifted highs and subterranean lows, and the use of lush, reverb‑heavy ambient interludes to heighten tension and reset the ear before the next rhythmic assault. The result is a sound that feels both mechanical and cinematic—aggressive yet spacious.

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.

Djent is a substyle of progressive metal defined by ultra-tight, low‑tuned, palm‑muted guitar riffs that create a percussive, onomatopoeic "djent" sound. It favors extended‑range instruments (7–9 strings), precise rhythmic subdivision, and a highly articulate, modern production aesthetic. Sonically, djent emphasizes polyrhythms, syncopation, and metric modulation, often pairing dense, chugging grooves with ambient clean guitars, spacious synth pads, and melodic choruses. Vocals range from harsh screams and growls to soaring cleans, while drums and bass lock tightly to the rhythmic grid, accenting the guitar’s staccato patterns. Although the term took off online in the late 2000s, the core rhythmic and timbral blueprint traces to the 1990s work of Swedish band Meshuggah.

Nu metal is a hybrid style that fuses the weight and riff-centric attack of heavy metal with hip‑hop rhythms, turntablism, funk bounce, and the angst‑laden melodicism of alternative rock. It favors down‑tuned, percussive guitar work, punchy bass lines, and groove‑heavy drum patterns over extended solos. Vocals often switch rapidly between rapped verses, shouted/screamed passages, and soaring melodic choruses. Production tends to be glossy yet bass‑forward, frequently incorporating DJ scratches, samples, electronic textures, and syncopated, hip‑hop‑influenced beats. Lyrical themes commonly explore alienation, trauma, social pressure, and catharsis. The result is an accessible but aggressive sound that emphasizes groove, dynamics, and hook‑writing as much as heaviness.

Progressive metal blends the ambition and extended song forms of progressive rock with the heaviness, timbre, and energy of heavy metal. It is characterized by complex arrangements, frequent time‑signature changes, virtuosic instrumental passages, thematic or concept‑driven albums, and a wide dynamic range from delicate, atmospheric sections to aggressive, high‑gain climaxes. Harmonically it draws on modal interchange, chromatic voice‑leading, and jazz‑fusion colors, while rhythmically it favors polymeters, polyrhythms, and metric modulation. Keyboards and layered production often add orchestral or cinematic scope.
