Parachute

English underground refers to a loose, DIY network of bands, audiences, promoters, and fanzines that coalesced in England in the late 1960s and 1970s. It fused heavy psychedelia, space-bound rock jams, anarchic proto‑punk attitude, and experimental folk and drone into an alternative to the mainstream British pop and rock industry. Rather than a single sound, it describes a culture: free festivals and communal gigs, improvised sets in squats and arts colleges, independent labels and press, and a commitment to countercultural ideals. Its music tends to favor long forms, trance‑like grooves, modal or drone harmony, tape and electronics experimentation, and lyrics steeped in surrealism, political dissent, and visionary imagery.

Psychedelic pop is a 1960s-born fusion that marries the hook-driven immediacy of pop with the timbral color, studio experimentation, and altered-perception aesthetics of psychedelic music. It favors concise song forms and memorable melodies while introducing unusual sounds (sitar, Mellotron, harpsichord), tape effects (backmasking, varispeed, flanging), and surreal or whimsical imagery. Compared to psychedelic rock, it is brighter, more tuneful, and radio-friendly, often wrapping adventurous production techniques in singable choruses and lush vocal harmonies.
