Pelagial was initially conceived as an instrumental album.

Pelagial is the sixth studio album by German metal band The Ocean.

The concept of Pelagial is multi-dimensional.

Pelagial was written as a single piece of music in order to fit the concept of a journey through the depth zones of the ocean.

The movie, which will also be incorporated into the visuals for the band's live show, features a female protagonist who embodies the psychological aspects of the lyrics for Pelagial.

Subsequent to the band recording the instrumental album, it was announced that Rossetti had recently recovered from a disorder affecting his voice and would indeed contribute vocals to Pelagial.

Pelagial has been generally well-received by critics, with About.com describing it as "a stunning collection of ideas and emotions" and Axis of Metal predicting that it would be a contender for album of the year in 2013.

Some editions of the album include a second disc featuring the all-instrumental version of Pelagial with an alternate mix.
