"Strange Days" is a psychedelic rock composition by The Doors, credited to the full band with lyrics by Jim Morrison and music primarily by Ray Manzarek and Robby Krieger. Composed during the band's intensive gigging period in 1965-1966, including nightly performances at venues like the Whisky a Go Go, the song was performed live as early as May 1966 before being recorded for The Doors' sophomore album of the same name on Elektra Records in 1967. Morrison's lyrics ponder the state of hippie youth culture and its perception by mainstream society, reportedly inspired by the band's visit to New York City, capturing an emotionally raw tone amid the flower-power era. Musically, the composition is built around an eerie organ riff from Manzarek that opens into a throbbing drum and bass groove, creating an unsettling, carnival-like atmosphere. The harmonic structure is notably restless, with the verse shifting keys three times, moving from E minor to G minor and resolving on E major, producing discomfiting movement that reinforces the song's themes of alienation. A significant production element is the early use of a Moog synthesizer to filter Morrison's vocals and add delay and echo effects, engineered by Bruce Botnick, making it one of the pioneering rock tracks to employ this technology for atmospheric purposes. The song exemplifies The Doors' dramatic, experimental approach to psychedelic rock on what many fans consider their most creatively adventurous album.
