Undercover is a Christian punk band 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."
Undercover started as a second-generation Jesus movement based band, associated with Calvary Chapel Costa Mesa and its Maranatha! Music record label. "God Rules," the title track of the second album, is the song that set apart Undercover in the Christian music scene from the rest of the "beginning" bands.
When Undercover released its first album in 1982, it was described by some as "Christian punk," characterized by high-energy anthems, rebellious themes, and short, three-chord songs. Mohawk hairstyles, tattoos, and torn jeans did little to convince people otherwise; nor did the next few albums, which contained punk versions of traditional hymns ("Holy Holy Holy"), shouted vocals ("God Rules"), and simplistic, direct lyrics ("Jesus is the Best"). The CCM Magazine review of their God Rules album claimed the band was New Wave rather than punk, as "the anarchy of punk is 180 degrees opposite of these boys."
