Resurrection Band, also known as Rez Band or REZ, was a Christian rock band formed in 1972. They were part of the Jesus People USA Christian community in Chicago and most of its members have continued in that community to this day. Known for their blend of blues-rock and hard rock, Resurrection Band is credited as one of the forerunners of the Christian metal genre. Christianity Today called them "the most influential band in Christian music history." Following their debut in 1978, the band's greatest popularity was during the early 1980s, but later in the decade they received some crossover success when they had two music videos featured on MTV.

Christian rock is a form of rock music that features lyrics focusing on matters of Christian faith, often with an emphasis on Jesus, typically performed by Christian individuals. The extent to which their lyrics are explicitly Christian varies between bands. Many bands who perform Christian rock have ties to the contemporary Christian music labels, media outlets, and festivals, while other bands are independent.
