The Sheila Divine is a Boston-based rock group. Critics compare their sound to the band's own heroes, mainly early 1980s post-punk. The band is most often noted for its loud/soft musical dynamic and Aaron's Perrino soaring vocals, screaming in key one moment and howling a falsetto the next. The band has a large die hard fan base in what is often called "the three Bs": Boston, Buffalo, and Belgium.

The band most often explains that they take the name from the Australian term "sheila", which denotes an effeminate man or wimp - thus making them in a literal sense, the sacred wimps. However there is also, in fact, a real live woman named Sheila Devine who Aaron, Jim, and Shawn were friends with at Oneonta State University.
