Spencer Chamberlain joined as lead vocalist

In 2003, Underoath supported the album’s release with their first inclusion on Warped Tour , however their participation in the tour came to an end when Taylor (under controversial conditions) was asked to leave the band. Dudley explained at that time that Taylor could no longer tour with Underoath for various reasons and left on his own decision. Under speculation of a potential breakup, the band then went on a supporting tour with Atreyu in August 2003 with Matt Tarpey as the temporary lead vocalist, while at the time being a part of Winter Solstice. In October 2003, at the CMJ Fest in New York City , the band reappeared with Spencer Chamberlain , formerly of the band This Runs Through, as the new lead vocalist. Chamberlain had toured with Underoath when fronting his former band and at one time was roommates with Dudley; their previous friendship with Chamberlain was considered when making him lead vocalist. Gillespie explained that before Chamberlain had been in the band, the group members “didn’t really get along”, however, after Chamberlain joined “everything was just normal, we clicked”. After Chamberlain became a permanent member, Underoath discussed the possibility of changing the name and becoming a new band. Ultimately, the members decided to remain as Underoath.
