Undercover is an American Christian punk band based in Fullerton, California, formed in the early 1980s by Joey "Ojo" Taylor and James "Gym" Nicholson. Through more than two decades and a few lineup changes, the band released eight studio albums and two live albums, and were pioneers in what would later be called Alternative music in the Christian world. The band was known for the spiritual growth shown in their music as their career progressed; CCM Magazine once called them "the band that grew up in public."
