Psychedelic music covers a range of popular music styles and genres, which are inspired by or influenced by psychedelic culture and which attempt to replicate and/or enhance the mind-altering experiences of psychedelic drugs. Broadly speaking, psychedelia generally employs non-naturalistic production techniques, which can include extreme stereo spatialization, reverb, reversed, phased, or flanged tape recordings, extensive editing, and extended improvisation. The music is often intended to have a disorienting or destabilizing effect, or to otherwise act on the listeners’ sense of “normalcy”. It emerged during the mid-1960s among folk rock and blues rock bands in the United States and Britain. .
