Psychedelic rock is a style of rock music inspired by or attempting to replicate the mind-altering experiences brought on by drugs such as cannabis, psilocybin, mescaline, salvia divinorum, and especially LSD. There are also other forms of psychedelic music that started from the same roots and diverged from the prevalent rock style into electronic music. In the history of rock music, psychedelic rock is a bridge from early blues-based rock to latter progressive rock and heavy metal.

However, an inner core of the psychedelic style of rock that came to public attention in 1967 can be recognized by characteristic features such as modal melodies; esoteric lyrics often describing dreams, visions, or hallucinations; longer songs and lengthy instrumental solos; and "trippy" electronic effects such as distortion, reverb, and reversed, delayed and/or phased sounds. Key albums that brought psychedelic rock into mainstream pop culture include The Beatles's Rubber Soul, Revolver, and especially Sgt. Pepper's Lonely Hearts Club Band.
