For the six men in Underoath, whose members have evolved and thrived during a decade-long progression that has elevated them into one of heavy music's biggest successes, change has been ubiquitous. 2010 has been no exception for the Tampa-based sextet, who underwent and overcame what many consider their most significant line-up alteration yet. In doing so, Underoath experienced an artistic rebirth in the form of O (Disambiguation). The band has delivered an album that emphatically surpasses, in terms of craftsmanship and cohesion, its predecessors which combined have sold well over 1 million copies. O (Disambiguation) is Underoath's new creative high watermark.
