One Hundred Hours was a Christian rock band from the United Kingdom formed by Tré Sheppard. The group's origins trace back to 1997 when lead vocalist Sheppard was invited to lead worship at a youth conference, which led to their first tour of California. Following this breakthrough, One Hundred Hours released two independent albums that sold over 16,000 copies each. In 2002, they signed with the Christian record label Survivor and released Cardiphonia, followed by Stronger Than My Heart in 2005. The band gained significant popularity through tours across the UK and Europe, including notable appearances at Spring Harvest and Soul Survivor festivals. They also supported Daniel Bedingfield on his UK & European tour in 2005. One Hundred Hours concluded their career with a performance at Soul Survivor Week C in 2009.
