The cause of death is unknown.
Joni Sledge, a founding member of the “We Are Family” disco quartet Sister Sledge, was found dead Friday at her home in Phoenix, Arizona. She was 60.
Publicist Biff Warren confirmed Sledge’s death, telling CNN that the cause is unclear. The singer’s family posted about her death on the group’s official Facebook account.
Born in Philadelphia, Joni was the second-oldest daughter of a Broadway tap dancer and an actress. She and her three sisters ― Debbie, Kim and Kathy ― performed in church before forming a touring group in 1971.
In 1979, working with masterminds of Chic, Nile Rodgers and Bernard Edwards, they hit the big time with the album “We Are Family,” whose title track peaked at No. 2 on the Billboard Top 100 chart and spawned many cover versions.
