For the first time ever, Retroactive Records brings Whose Side You On? by Giantkiller to CD, a treasured release for fans of Jesus Music, early Christian rock, and CCM. Originally released in 1981 in the U.K. on Chapel Lane Records (and later re-titled Valley of Decision for U.S. distribution by Star Song), this album is the second by this pioneering U.K. Jesus Music band. Ranked at #265 on CCM's 500 Best Albums of All Time, Whose Side You On? represents a powerful moment in Christian rock history, blending passionate lyrics with the raw edge of early rock. Giantkiller's sound captures the spirit of Christian Euro rock contemporaries like Ishmael, The Predators, Bill Mason Band, and Alwyn Wall, while resonating with fans of early DeGarmo & Key, Lifesavors, Undercover, The Imitators, and The Choir. The album was mixed by Christian rock veterans Kemper Crabb (of Arkangel-Warrior fame) and Jimmy Hotz (known for Beyond the Crystal Sea), with Hotz producing the album in Houston, TX. In 2021, Hotz remastered the original master tapes from scratch, elevating the audio quality for a modern listening experience. This reissue includes heartfelt reflections from lead guitarist Pete Gilgan and original producer Jimmy Hotz, along with a band biography to reintroduce fans to the groundbreaking sound of Giantkiller. For those who cherish the origins of Christian rock, Whose Side You On? is a must-have gem, filled with a spirit that continues to inspire today.
