Oceanic (2002–2004) Whereas Celestial was still deeply rooted in heavy metal and hardcore, 2002's follow-up, Oceanic, saw the band acquire new characteristics comparable to post-rock and ambient music, significantly aiding in the birth of the genre of post-metal in what many saw as a logical progression.
