Best known for their work with Chic in the late 1970s, siblings Debbie, Kim, Joni and Kathy Sledge reached the height of their popularity during the disco era but had been recording since the early 1970s and were still active in the late 1990s.

The group was formed in Philadelphia in 1971, when the sisters' ages ranged from 12 to 16, and they recorded their first single. In 1972, they signed with Atco and recorded their second single, Weatherman, which was followed by Mama Never Told Me in 1973.

Sister Sledge's first national hit came in 1974 when Love, Don't You Go Through No Changes on Me reached number 31 on the R&B charts and they recorded their debut album, Circle of Love. Their second album, Together, was released in 1977.

It wasn't until 1979, when Chic leaders Nile Rodgers and Bernard Edwards produced We Are Family, that Sister Sledge really exploded commercially. He's the Greatest Dancer and We Are Family both reached number one on the R&B charts.

Their next album, Love Somebody Today (1980), was also produced by Rodgers and Edwards.

In 1981, Sister Sledge switched producers and worked with Narada Michael Walden, who produced 1981's All American Girls.

The group's popularity began to decline after 1982. They left Atlantic in 1985, but the four kept busy in the 1990s. Epic released Kathy's debut solo album, Heart, in 1992, and in 1997 the sisters recorded a risk-taking album, African Eyes, arguably one of the finest they ever recorded.
