Passage: Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.
