The concept of the album is made evident in its title, Pelagial. Listeners will be further submersed as they journey with the band, beginning at the surface of the ocean and plunging through all five pelagic depth zones: epipelagic, mesopelagic, bathyalpelagic, abyssopelagic, and hadopelagic. In synch with diminishing light and increasing pressure as one dives or sinks deeper into the ocean, the album begins rather light and progressively gets heavier and slows as the band reaches the unfathomable depths of the hadopelagic zone, characterized by complete darkness and a thousandfold increased pressure as compared to surface level.
