Stryper is an American Christian heavy metal band from Orange County, California. The group's lineup consists of Michael Sweet (lead vocals, guitar), Oz Fox (guitar), Tim Gaines (bass guitar), and Robert Sweet (drums). In 2004, Gaines left the band and was replaced by Tracy Ferrie (bass guitar) but rejoined in 2009.

Formed in 1983 as Roxx Regime, the band soon changed their musical message to reflect their Christian beliefs, and the band's name was also changed to Stryper. They went on to become the first overtly Christian heavy metal band to gain acceptance in the mainstream.
