Joan Elise "Joni" Sledge (September 13, 1956 – March 10, 2017) was an American singer, songwriter and record producer best known as a founding member of the family vocal group Sister Sledge. During a career that spanned several decades she contributed both as a vocalist and as a creative force behind the group's recordings. Sister Sledge achieved lasting popular recognition with hits such as We Are Family and He's the Greatest Dancer, songs that helped define late 1970s disco and remain widely recognized cultural touchstones.

Early life and musical beginnings

Sledge was born in Philadelphia and grew up in a musical household. She and her sisters formed Sister Sledge in the early 1970s, combining family harmonies with contemporary pop, soul and disco influences. Joni pursued part-time studies at Temple University while developing her performance skills, and the group's early exposure included television appearances and club dates that helped them build a national profile.

Career highlights and contributions

As a member of Sister Sledge, Joni sang lead and harmony on a range of recordings across pop, R&B and dance music. She was also active offstage as a songwriter and producer. Notably, she performed the song "Then Came You" with the Spinners on the television music program The Midnight Special in 1975, an early example of her collaborative work with other established acts. Later in her career she turned toward writing and production for the group, contributing original material and helping shape their sound.

Songwriting, production and later work

Joni Sledge wrote and produced material for Sister Sledge compilations and new releases. She composed the track "Brother, Brother Stop," which appeared on a Sister Sledge greatest-hits collection and was credited to her as songwriter and producer. Her production work on the album African Eyes (released in the late 1990s) drew critical attention and was recognized by the recording industry with a nomination related to production excellence. These activities illustrated her evolution from performer to behind-the-scenes creative lead.
