prEVOLVEr: The Mixtape

Ratchet music is a minimalist, club-focused strain of West Coast hip hop that coalesced in the early 2010s, most closely associated with Los Angeles producer DJ Mustard. It emphasizes sparse drum programming built from 808 kicks, handclaps, crisp hi‑hats, and simple percussive fills; bouncy tempos around 95–105 BPM; short, catchy synth or piano stabs; and a weighty sub‑bass that leaves ample space for vocals. Culturally and lyrically, it channels “ratchet” party culture and slang—rooted in Louisiana (notably Shreveport’s nickname “Ratchet City”) and amplified by the L.A. party scene—favoring braggadocio, nightlife, flirtation, and chant‑able hooks over dense lyricism. The result is a stripped‑down, hook‑driven sound engineered for dance floors and radio rotation.

The Wave is a loosely defined cluster of American post-hardcore/emo bands that surged in the early 2010s as emo-pop’s mainstream moment faded. The name was a tongue‑in‑cheek scene tag that stuck in press coverage, but it points to a real overlap in sound, ethos, and touring networks. Musically, The Wave fuses the urgency of 1990s post‑hardcore and screamo with confessional, literate lyric writing associated with emo. Expect shouted or half‑sung/half‑spoken vocals, dynamic quiet‑loud builds, intricate but driving drums, and guitar textures that shift between glassy clean arpeggios and overdriven, emotive climaxes. The songs often emphasize catharsis, narrative detail, and community-minded DIY presentation.

Tread is a micro-style of trap characterized by icy, futuristic synth palettes and extremely busy, high‑tempo drum programming built around distinctive 808 patterns. Producers favor cold pads, glassy bells, FM keys, and clipped, digital textures that feel mechanical but still swing. The sound coalesced around the Philadelphia collective Working on Dying in the mid‑2010s and spread through SoundCloud before surfacing on mainstream projects. Compared with other trap variants, tread is lean and minimal in harmony, yet aggressive in rhythm and sound design, creating a stark, nocturnal mood that still bangs in a club context.
