"Experiment in Terror" is an instrumental song composed by American composer Henry Mancini for the 1962 suspense-thriller film Experiment in Terror directed by Blake Edwards and starring Glenn Ford and Lee Remick. Mancini composed the musical score for the entire film, with "Experiment in Terror" being the main theme.
Association with Lana Del Rey Edit
Del Rey uses the song as an intro for her 2018 LA to the Moon Tour shows. It plays before she walks on stage at each show to build suspense before she performs "13 Beaches", the first song on the setlist.
