Underoath (occasionally typeset as underOATH or UNDERØATH) is an American band originally formed on November 30, 1997 in Ocala, Florida, but later relocated to Tampa, Florida, which was home to some of their newer members.
During the band's early years, when they were fronted by former vocalist Dallas Taylor, Underoath displayed a heavier style than their later, more well-known work, incorporating disparate influences from death and black metal. With Taylor, they released Act of Depression, Cries of the Past, and The Changing of Times. Following Taylor's departure, Spencer Chamberlain became lead vocalist. The band then released They're Only Chasing Safety and Define the Great Line, gaining a certified gold rating and the highest-charting Christian album on The Billboard 200 since 1997, respectively. These two albums have given them more mainstream and commercial success. They're Only Chasing Safety marked an extreme departure from their earlier work, with extensive use of clean vocals and poppy rhythms, and a near-complete eradication of breakdowns and the use of double-bass. Define The Great Line reflected another shift in style, once again incorporating heavier styles into Underoath's sound. While the album still featured extensive clean vocals, its use of heavier vocals, detuned guitars, and Botch-inspired guitar work paved the way for Underoath's future.
Underoath released a live album called Survive, Kaleidoscope on May 27, 2008. Earlier that year, the band recorded a new studio album called Lost in the Sound of Separation, which was released on September 2, 2008, peaking at number 8 on the Billboard 200. In April 2010, Aaron Gillespie announced his resignation from the band, stating that there are no hard feelings and that he will continue to pursue his other band, The Almost, leaving Underoath with none of its founding members.
In October 2012, Underoath announced that they would be disbanding the following year, in addition to a career-spanning compilation album, Anthology: 1999–2013, which was released on November 6, 2012. The band then embarked on a nine-date farewell tour, which wrapped up at Jannus Live in St. Petersburg, Florida on January 26, 2013.
In January 2015, the band launched a campaign to finalize production of documentary film about their farewell tour of 12 shows, posting two trailers on that subject to their YouTube channel.
In July 2015, Underoath began teasing the phrase "rebirth is coming" and an accompanying cryptic video across their social media accounts. The audio portion to the cryptic video, when played backwards, turned out to be the chorus for "It's Dangerous Business Walking Out Your Front Door" off the band's 2004 album They're Only Chasing Safety, and later a countdown timer ending on August 24, 2015 later appeared on the band's website.
On August 17, 2015, the band's first show since disbanding in 2013 was announced, headlining the Self Help Fest in San Bernardino, California on March 19, 2016, along with A Day to Remember. In an interview article for Alternative Press, Chamberlain and Gillespie confirmed that the band was reuniting.
