Psychedelic CDs, Music, Collection and LPs  

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. The album that brought psychedelic rock into mainstream pop culture was The Beatles's Revolver.

While the first musicians to be influenced by psychedelic drugs Were in the jazz and folk scenes, the first use of the term "psychedelic" in popular music was by the "acid-folk" group The Holy Modal Rounders in 1964. The first use of the word "psychedelic" in a rock music context is usually credited to the 13th Floor Elevators, and the earliest known appearance of this usage of the word in print is in the title of their 1966 album The Psychedelic Sounds of the 13th Floor Elevators. The psychedelic sound itself had been around at least a year earlier in the live music of the Grateful Dead and Pink Floyd, and Donovan's hit Sunshine Superman.
