Psychedelic music was first created by musicians who, aided by an intake of various opiates and mind-altering substances, endeavoured to explore the sonic possibilities of music. Progressive rock followed, an attempt - aided this time by a shift in emphasis from the single format to albums - to create a serious, artistically superior strain of music, unrestricted by the thee-minute format and with an emphasis on musical virtuosity. Punk killed it. Kind of.
