The Universal Migrator parts I & II were released at the same time, but were for sale independently. Part I: 'The Dream Sequencer' mainly features laid-back, atmospheric material with songs focussing on melody. Initially the album was meant to only feature female singers, but not enough singers were available so Arjen changed his plans.



Whereas 'Into the Electric Castle' has an opera-like set up, in which main characters sing dialogues in one song, on 'The Dream Sequencer' Arjen chose to have only one vocalist sing each song. As a result each new incarnation of the last Colonist on Mars, the main character of the story, has its own distinct personality.
