Initially, The Breeders were conceived as a way for Pixies' bassist Kim Deal and Throwing Muses' guitarist Tanya Donelly to let out some suppressed creative energy. Deal and Donelly both played guitar, leaving bass for Josephine Wiggs of Perfect Disaster. Taking their name from the group Deal led with her twin sister, Kelly, in their teens, the Breeders combined the spareness of Throwing Muses with the shifting dynamics and warped pop sensibilities of the Pixies. Pod, their critically acclaimed debut album, was released in 1990. Two years later, the group delivered Safari, a 4 song EP that found the band getting more muscular and melodic. Soon after its recording, Donelly left the Breeders to form her own group, Belly. Kim brought in her sister, Kelly, as her replacement. By this time, their permanent drummer was Jim MacPherson.
