In 2002, Takehold licensed all of its bands and releases to Seattle's Tooth & Nail/Solid State label. Underøath hit the studio and recorded the ten songs that would comprise their first album under the new partnership, appropriately titled The Changing of Times. Taylor abruptly left the group in the middle of 2003's Warped Tour, leaving distressed fans contemplating the band's uncertain future. Underøath -- which also included bassist Grant Brandell and guitarist James Smith -- continued on, however, enlisting ex-This Runs Through member Spencer Chamberlain as their new vocalist.
A year later, the new lineup released They're Only Chasing Safety and supported it on the road with bands like Thrice, the Bled, Hopesfall, and Fear Before the March of Flames. A special edition of the album was next released in fall 2005 that included four bonus tracks; touring continued with a spring 2006 headlining tour alongside Poison the Well, As Cities Burn, and others. Deciding to stick with Tooth & Nail instead of jumping to a major label, the sextet showcased substantial growth and maturity on its next effort, Define the Great Line, issued in June 2006. A heavier, more emotional album than the breakout success of 2004's Chasing Safety, the record sold close to 100,000 copies in just its first week of release and was certified gold by the year's end. Embraced by fans and critics alike and considered the band's masterpiece by many, the group supported it on Warped's main stage that summer.
But with a month of dates remaining, tensions within Underøath's ranks suddenly came to a head, causing them to drop off the traveling festival. Rumors swirled of their impending breakup, but the guys remained adamant that a much-needed break was merely due to sort things out. They proved themselves by returning in 2006 with Define the Great Line. Climbing all the way to number two, the album became the highest-charting Christian album on the Billboard 200 since 1997 when LeAnn Rimes took the number one spot with You Light Up My Life. Underøath returned to the studio in 2008 for Lost in the Sound of Separation, an 11-song behemoth of a record that saw the group adopt a darker, more experimental (yet still undeniably heavy) sound. In 2009 drummer/vocalist Aaron Gillespie left the group, and was replaced by ex-Norma Jean drummer Daniel Davison. Ø (Disambiguation), the group's seventh full-length recording, arrived the following year. ~ Ryan J. Downey, Rovi
