This is the most mellow track from Black Sabbath's nineteenth album, 13. Critics have compared its processed vocals, spacey motif and Django Reinhardt-influenced soloing to that of "Planet Caravan" from 1970's Paranoid.
The word 'Zeitgeist' is derived from the German 'Zeist' meaning "time'' and "Geist" meaning "spirit." It is used to describe the dominant moral or intellectual school of thought characteristic of a culture during a particular period in time. Manic Street Preachers bass guitarist and lyricist Nicky Wire sings of the term on the title track of his 2006 solo album I Killed The Zeitgeist:
"I killed the zeitgeist Ground it all to dust Left myself alone Digging deeper holes."
