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.

Classic psychedelic rock is the mid-to-late 1960s strain of rock that sought to mirror and magnify altered states of consciousness through sound. It favored saturated guitar tones, feedback, drones, and studio trickery (reverse tape, tape echo, flanging) alongside non‑Western timbres such as sitar and tambura. Emerging on the U.S. West Coast and rapidly flowering in both San Francisco and London, the style became the soundtrack to the counterculture—expansive, exploratory, and often modal, with extended jams, surreal imagery, and high volume. It encompassed both the harder "acid rock" club sound and the more whimsical, pop‑structured British variant.
