In the Bible, Jesus brings Lazarus back from the dead. This song is about a woman who has died, but comes back in spectral form to reclaim her son. The lyric finds her trying to convince him to follow her to the underworld.
Porcupine Tree lead singer Steven Wilson
wrote the song for a film he was working on with his friend, Mike Bennion, but when financing fell through, Wilson used some of the tracks, including "Lazarus" as Porcupine Tree songs.
