This moody track begins with a recording from Apollo 17. We hear the crackled voice of Captain Eugene Cernan, the last man to have walked on the moon, gasp: "A bright object. Rotating in rhythmic fashion. Look back on the earth... There's something out there." Daft Punk commented to French publication Le Nouvel Observateur: "It is a voice that literally just space. And it speaks for itself ..."
The song was co-produced by French DJ and producer DJ Falcon, who also plays modular synthesizer on the track. Falcon and one-half of Daft Punk, Thomas Bangalter, formed a house duo called Together that released two tracks in the early 2000s on Bangalter's own label.
DJ Falcon told NME the story of the moment that they finished this song: "When we came to finally listen to the finished track in the studio," he recalled, "we could feel the intensity the noise was causing. Right at the end of the track, the speakers in the studio blew out! I'm talking like one second left. That's the end of the album! It was such a rock n' roll vibe, like smashing your guitar at the end of the show. The studio was f---ed up, but we just smiled at each other and said, 'F--k that!' We closed the door on the studio and went home."
"We Ride Tonight" by Australian rock band, The Sherbs is sampled at the beginning of this track.
