Stoner rock is a heavy, riff‑centric style that blends the weight and doom of early heavy metal with the groove and expansive jams of late‑60s/70s psychedelic and acid rock. It is marked by fuzz‑drenched, down‑tuned guitars, thick bass tones, and relaxed but powerful mid‑tempo grooves. Songs often emphasize hypnotic, repetitive riffs; extended instrumental passages; and a warm, vintage analog sound. Vocals tend to be laid‑back or gritty rather than operatic, and lyrical themes commonly explore the desert, space, altered states, mythology, and countercultural imagery. The overall vibe is earthy and immersive—equal parts head‑nodding groove, psychedelic haze, and Sabbath‑born heaviness.

Acid rock is a heavier, louder, and more improvisation-driven branch of psychedelic rock that emerged in the mid-to-late 1960s. It is characterized by extended guitar solos, distorted and feedback-laden textures, modal or drone-based harmony, and a strong emphasis on trance-inducing grooves. The style was closely tied to the counterculture and LSD-fueled happenings of the era, particularly on the U.S. West Coast. Musically, it blends blues-rock’s grit, garage rock’s raw energy, folk-rock’s modal harmonies, and raga-influenced drones, then amplifies everything—volume, duration, and intensity—into hypnotic, often explosive performances.

Hard rock is a loud, riff-driven style of rock music built around heavily amplified electric guitars, a powerful rhythm section, and assertive vocals. Songs typically center on memorable, blues-based guitar riffs, strong backbeats, and energetic, often shouted or belted choruses. The genre emphasizes power, groove, and visceral impact over intricate harmony or extended improvisation. Distortion, power chords, pentatonic melodies, and call‑and‑response between vocals and guitar are core traits, while lyrical themes often explore rebellion, lust, swagger, escape, and cathartic release.

Proto-punk is a catch-all term for the raw, stripped-down rock that immediately preceded and inspired punk rock. It favors abrasive guitar tones, primitive drumming, short song forms, shouted or deadpan vocals, and lyrics steeped in alienation, anti-establishment anger, and street-level realism. Emerging from 1960s garage rock, avant-leaning art rock, and hard-edged rhythm & blues, proto-punk connected the chaos of early rock and roll with the urgency of the 1970s punk explosion. Its sound ranges from the Detroit ferocity of The Stooges and MC5 to the arty minimalism and noise experiments of The Velvet Underground.

The San Francisco Sound refers to the distinctive, improvisation-heavy psychedelic rock that emerged from the San Francisco Bay Area—especially Haight-Ashbury—during the mid-to-late 1960s. It is characterized by long, modal jams; a live-first ethos; prominent use of electric guitars with feedback and distortion; fluid, conversational improvisation among players; and a communal, countercultural sensibility. Bands frequently blended blues, folk, country, R&B, jazz, and raga influences, often incorporating droning textures, extended solos, and striking dynamic arcs. The scene was as much about place and community as sound: Bill Graham’s Fillmore, the Avalon Ballroom, light shows, the Acid Tests, underground FM radio, and Owsley Stanley’s high-fidelity sound systems all helped forge a large-room, enveloping live aesthetic that came to define the movement.

The Haight-Ashbury scene refers to the mid-to-late 1960s countercultural music community centered in the Haight-Ashbury neighborhood of San Francisco, California. Closely tied to the hippie movement, it fostered long-form, improvisational rock infused with folk, blues, raga, and experimental elements—what became known worldwide as the San Francisco sound. Musically, bands emphasized communal performance, extended jams, modal harmony, and exploratory guitar tones shaped by fuzz, feedback, and reverb. Lyrically and culturally, the scene embraced psychedelic consciousness, anti-war politics, free love, and communal living, with landmark gatherings like the Human Be-In and the Summer of Love helping to broadcast the sound and ethos globally.
