John Bunyan's Progressive Pilgrims

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.

Psychploitation is a late-1960s studio-driven, budget-conscious offshoot of psychedelic rock that "exploited" the era’s fascination with mind-expansion and far-out sounds. Issued largely by budget and library labels, these LPs were often credited to ad‑hoc studio projects and session players. The music foregrounds fuzz guitars, Farfisa/Vox organs, electric sitar, droning tambura, vibraphone, heavy spring reverb, tape delay, and ping‑pong stereo effects. Tracks tend to be instrumental or minimally voiced, groove-led, and hooky—sometimes covers of current hits—designed as sonic spectacles to sell the psychedelic idea as much as a band. Aesthetically, psychploitation blurs garage-rock grit, lounge/easy listening sheen, exotica motifs, and soundtrack/library sensibilities. Today it’s prized by crate-diggers for its kitsch-meets-innovation charm, sample-ready breaks, and vivid period production.
