The Casualties were formed in 1990, with original members Jorge Herrera (vocals), Hank (guitar), Colin Wolf (vocals), Mark Yoshitomi (bass) and Yureesh Hooker (drums). The members aimed to return to what they viewed as the "golden era" of street punk, embodied by bands such as The Exploited and Charged GBH, which they believed had disappeared by 1985.[3] During the early years, the lineup was fluid, with several changes.
