Kraftwerk fans are used to hearing otherworldly tunes, but the German electronic music pioneers took it to another level at a gig in Stuttgart.
Video posted Saturday by the European Space Agency shows German astronaut Alexander Gerst "dropping in" for a live performance from the International Space Station.
Using a tablet computer with a virtual synthesizer, Gerst played a duet of Kraftwerk's 1978 song "Spacelab" with the band Friday night to cheers from the audience.
He's not the first space musician. Canadian astronaut Chris Hadfield recorded a cover of David Bowie's "Space Oddity" and played a duet with the Barenaked Ladies while 400 kilometers (250 miles) above the Earth in 2013.
