Pelagial

Pelagial is the sixth studio album by German post-metal band the Ocean. It is a concept album with the track titles referencing, in descending fashion, the oceanic depth zones. Musically, the concept is explored by sequencing the music such that it is increasingly dark and claustrophobic in emulation of the diminishing light and increasing pressure that comes with oceanic descent. The album was initially conceived as an instrumental release, although vocals were subsequently added; the band has made both versions available.
