Underoath (sometimes stylized as underOATH or UnderØATH) is a Grammy-nominatedmetalcore/post-hardcore band from Tampa, Florida, formed in 1998. The band's line-up consists entirely of Christian members. They are currently signed to Solid State Records and are the label's best selling band.
After several line-up changes, Underoath's only original member is drummer Aaron Gillespie. During the band's early years, when they were fronted by former vocalist Dallas Taylor, Underoath displayed a more deathcore sound with their music, with double-bass drums and breakdowns. With Taylor, they released Act of Depression, Cries of the Past, and The Changing of Times. Following his 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 have recorded a live CD/DVD album called Survive, Kaleidoscope, which was released on May 27, 2008. From late February to early May 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.
