“Planet Caravan”

“Black Sabbath’s Geezer Butler, who composed the song’s lyrics, has stated that the song is about floating through the universe with one’s lover. Black Sabbath lead vocalist Ozzy Osbourne uses a Leslie speaker to achieve the vocals’ treble and vibration effects. Iommi overdubbed flute to the reversed multitrack master which was then re-forwarded and treated with stereo delay.

On 31 May 2020, “Planet Caravan” was selected by SpaceX as the wake-up music for the crew of a SpaceX Crew Dragon prior to the craft’s launch later that day. It represented the first time astronauts have received a musical wake-up since the final shuttle mission in July 2011. The craft was bound for the International Space Station.”
