Universal Migrator, Part 2: Flight of the Migrator

Universal Migrator Part 2: Flight of the Migrator is a progressive metal album released in 2000 by Dutch multi-instrumentalist Arjen Lucassen, and is the fifth album of his Ayreon project.
The musical styles found on Flight of the Migrator contrast its counterpart The Dream Sequencer, illustrating a wild, raucous journey through the tumultuous and chaotic reaches of outer space. In keeping with the setting of the story, the album's tone is much heavier, exuding a powerful, guitar-driven metal feel throughout.
Both albums were released simultaneously, sold well and were received positively. In 2004, Lucassen moved to a new record label - InsideOut Music - and with this move came re-issues of all the previous Ayreon releases, including The Dream Sequencer. The special edition re-issue merged both albums into a single release, titled Universal Migrator: Parts I & II. The album was also released on vinyl on December 2012.
As Universal Migrator had enough content to form a two-CD album, Lucassen decided to sell each disc as a separate release. He believed his fans to be fundamentally divided into two groups by genre of choice, being either progressive rock or heavy metal fans. The Dream Sequencer was meant to appeal to the prog enthusiasts, and Flight of the Migrator to the metal fans, so that each could simply purchase the album of their choice, if so inclined, and to his surprise both fanbases bought and enjoyed both albums.
