Psychedelic rock is a subgenre of rock music that originally emerged during the mid-1960s, inspired by psychedelic culture and primarily centered 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.
