Psychedelic pop (or acid pop)[3] is a genre of pop music that contains musical characteristics associated with psychedelic music.[1] Developing in the mid-to-late 1960s, elements included "trippy" features such as fuzz guitars, tape manipulation, backwards recording, sitars, and Beach Boys-style harmonies, wedded to melodic songs with tight song structures.[1] The style lasted into the early 1970s.[1] It has seen revivals in subsequent decades by neo-psychedelic artists.[2]
