Psychedelic rock
genre of rock music
Psychedelic rock is a subgenre of rock music that originally emerged during the mid-1960s, inspired by psychedelic culture and centered primarily around the influence of psychoactive and hallucinogenic drugs. The music incorporated new electronic sound effects and recording techniques, extended instrumental solos, and improvisation. Many psychedelic groups differ in style, with the label often applied spuriously.
Originating in the mid-1960s among British and American musicians, the sound of psychedelic rock invokes three core effects of LSD: depersonalization, dechronicization (the bending of time), and dynamization (when fixed, ordinary objects dissolve into moving, dancing structures), all of which detach the user from everyday reality. Musically, the effects may be represented via novelty studio tricks, electronic or non-Western instrumentation, disjunctive song structures, and extended instrumental segments. Some of the earlier 1960s psychedelic rock musicians were based in folk, jazz, and the blues, while others showcased an explicit Indian classical influence called "raga rock". In the 1960s, there were two main variants of the genre: the more whimsical, surrealist British psychedelia and the harder American West Coast "acid rock". While "acid rock" is sometimes used interchangeably with the term "psychedelic rock", it also refers more specifically to the heavier, harder, and more extreme ends of the genre.
The peak years of psychedelic rock were 1967 to 1969, with milestone events including the 1967 Summer of Love and the 1969 Woodstock Festival, spearheading an international phenomenon that birthed a widespread counterculture and the hippie movement before declining as changing attitudes, the loss of some key individuals, and a back-to-basics approach led surviving performers to move into new musical areas. The genre bridged the transition from early blues and folk-based rock to progressive rock and hard rock, and as a result contributed to the development of sub-genres such as heavy metal.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q206159. The Library of Congress control number is sh95010207. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1967 and 1969.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
