Perpetuum Mobile is a studio album by the industrial band Einstürzende Neubauten. It was released in 2004 on Mute Records. The album is an offshoot of the band's first fans-only recording experiment, and was released in part to facilitate a world tour.
Perpetuum Mobile contains overarching references to its namesake perpetuum mobile (the musical term) and to perpetual motion (the physical concept). Other ideas include Boreas, Ararat (of note both for the Einstürzende Neubauten song "Armenia" and Mount Ararat), travel and airplanes, and rare birds.
