The Casualties formed in 1990 out of a desire to return to the heyday of punk, an era that hung on into the early '80s and then started to fall by the wayside in favor of the very early grunge movement, as well as hair metal, synth pop, and new wave. But the band's lineup was far from stable in the early days. The initial lineup consisted of singers Jorge Herrera and Colin, drummer Yureesh, guitarist Hank, and bassist Mark. Even this inaugural lineup was shaky, with Colin stepping out for several months to finish his education, and Rivits singer Rachel stepping in to take his place. During this period, the Casualties put together a demo. The following year, the core lineup consisted of Colin, Jorge, Yureesh, and Mark. The band added guitarist Fred when Hank dropped out, and went on to make an appearance on the compilation Benefit for Beer. Soon more changes were in the works, with new guitarist Fred heading off to school. C Squat's Scott temporarily filled Fred's shoes until he returned a short time later. During this period, guitarist Hank came and went a second time. Another guitarist, Steve, also played briefly with the group.
