Crimpshrine was an American punk rock band from Berkeley, California. The group was formed in 1982 by Aaron Cometbus, founder of the seminal punk rock zine Cometbus, and future Operation Ivy vocalist Jesse Michaels. They grew out of the East Bay scene, centered on 924 Gilman Street, and had an important influence on later East Bay bands such as Operation Ivy, Green Day and punk rock in general.
