Zao is an American metalcore band founded in Parkersburg, West Virginia and later relocated to Greensburg, Pennsylvania. Founded in March 1993, Zao has hosted several musicians and endured numerous roster changes to the point where no original members remain. Former drummer Jesse Smith, singer Dan Weyandt, and guitarists Scott Mellinger and Russ Cogdell are seen by some fans as the "core" of Zao, with the current line up being the longest running in the band's history.
