"Hallo Spaceboy" is a song by the English musician David Bowie from his 20th studio album, Outside (1995). It originated as an instrumental by Reeves Gabrels called "Moondust", which Bowie and Brian Eno stripped down and used to form the final track. An industrial rock and electronica track influenced by the Pixies and Nine Inch Nails, the song contains a hypnotic sound, with synthesisers, loops and distorted guitar lines. Lyrically influenced by Brion Gysin, the song contains images of apocalypse and continues the androgynous conundrums of former Bowie songs such as "Rebel Rebel".
