Vicki Peterson, guitarist for the Bangles, isn’t afraid to admit that she wasn’t keen to re-form the all-female group that became one of the hottest pop groups of the 1980s. Sure, the band Peterson founded in 1981 with her sister Debbi on drums and friend Susanna Hoffs as frontwoman, was a sensation and had major hits including “Walk Like an Egyptian” and “Manic Monday.” Yet when the band broke up in 1989, Peterson was ready to move onto other music. She did just that, playing with the rock group Continental Drifters and forming the Psycho Sisters with Susan Cowsill, her best friend and sister-in-law since 2003.

“There were many, many years where my line was you couldn’t pay me enough to cover the therapy I’d need to sing ‘Walk Like an Egyptian,’ ” said Peterson from the California home she shares with husband and Beach Boys drummer John Cowsill. “In the late 1990s when Susanna was coming around with increasing frequency saying, ‘I know you’re not interested, but if we did re-form … ,’ I said that I would only be interested if we were still creating music and we were still a viable band. I’m not interested in nostalgia.”
