Carpenter was born in New Haven, Connecticut, and moved to Downey, California, in 1963 with her family. She began to study the drums in high school and joined the Long Beach State choir after graduating. After several years of touring and recording, Carpenters were signed to A&M Records in 1969, achieving commercial and critical success throughout the 1970s. Initially, Carpenter was the band's full-time drummer, but gradually took the role of frontwoman as drumming was reduced to a handful of live showcases or tracks on albums. While Carpenters were on hiatus in the late 1970s, she recorded a solo album, which was released years after her death.
