A piano and orchestral piece leading into "Survival". Bears similarities to Chopin's Etude Opus 10 no 3.
The name of the song was unknown until the Interview with BBC1 about "Survival" was made. On some promo CDs for "Survival", the song is merged into a single track with "Survival" as the 'album version'. The song made no appearances during The 2nd Law Tour, despite Survival being played. However Prelude was played as a intro to Starlight at nearly every Drones Tour concert, Survival didn't make any appearances though.
