Stryper is a Christian metal band from Orange County, California. The group's lineup consists of Michael Sweet (lead vocals, guitar), Oz Fox (guitar), Perry Richardson (bass guitar), and Robert Sweet (drums).

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.

In 1983, they signed with major label Enigma Records and released their debut album The Yellow and Black Attack. In the mid-1980s, Stryper enjoyed their most successful period beginning with the release of To Hell with the Devil, which achieved platinum sales status.

During the 1980s, Stryper represented the popular glam metal style of the time, characterized by highly visual performances, twin guitar solos, Sweet's high-pitched, multi-octave screams and big hair.

A characteristic element of the band was that all their outfits, sets, and instruments were painted in yellow and black stripes. Stryper went on to release two more gold albums before disbanding in 1992.

In 2003, Stryper came out of retirement for a reunion tour and subsequently signed a multi-album contract with Big3 Records in 2005. In 2013, they signed a multi-album deal with Frontiers Records, and have released Second Coming, which includes 14 re-recorded songs from their first three albums.

They have also released a number of albums containing new material: 2013's No More Hell to Pay, 2015's Fallen, and 2018's God Damn Evil. The name "Stryper" derives from Isaiah 53:5 in the King James version of the Bible: "But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
