The four Sledge sisters – Debbie, Joni, Kathy and Kim – were born and raised in Philadelphia. “It is the root of where everything started,” Debbie said in 2023. “I grew up in a very musical family, plus we all had an energy that was so unique. Despite having aunts, uncles, grandparents who all performed – some professionally – the most formative thing is that we sang for fun.” As the best Sister Sledge songs prove, this tight-knit shared history translated into some of disco’s most enduring classics.
“It was a really cool community that we grew up in,” Joni said, speaking of Philadelphia itself. “It wasn’t a very wealthy area but we had a lot of fun hanging in the streets. And that’s where we learned to sing.” The Sledge sisters found joy in singing, expressing bliss through their voices and treasuring the sensation of joining together as a family unit.
Although there are brilliant tracks to be found in their earlier releases, Sister Sledge’s classic period starts in 1979, with the release of the album We Are Family and the beginning of their working relationship with Nile Rodgers and Bernard Edwards of Chic. Rodgers and Edwards were at the apex of their career, and the sisters sometimes found the older, self-assured producers intimidating.
“In the studio with Nile and Bernard, it was a really big challenge. First of all, they were so talented. I call them geniuses,” Kim has said. “But there was a lot of learning what it’s like to work with producers, who saw things a certain way.” The Sledge sisters valued discipline and preparation; the Chic duo favoured spontaneity. While the four siblings loved harmony singing, Edwards and Rodgers liked the sound of unity. But, as all parties worked through their approach, magic was created. The sisters’ ability to bring their own personalities to those Chic-produced records are a very big part of what defines the best Sister Sledge tracks today.
Joni Sledge passed away in 2017. Debbie and Kim have continuously sung in the group since its formation, and Kathy has rejoined her sisters at various points, while also pursuing a solo career. “I remember saying, back then, wow this is such a blessing,” Kathy reflected in 2021. “We set the pace for the Spice Girls and TLC and En Vogue.”

10: Frankie (from ‘When The Boys Meet The Girls’, 1985)
This playful track is markedly softer than the cutting-edge disco-funk that characterises many of the best Sister Sledge songs. Its nostalgic feel nevertheless sits very squarely in the mid-80s alongside other affectionate girl-group pastiches of the time, such as Madonna’s hit 1986 single True Blue. Frankie proved particularly popular in the UK, where it spent five weeks at No.1.
However – and probably because it was so far removed from Sister Sledge’s earlier, cooler material – both the group and their producer at the time, Nile Rodgers, were initially ambivalent about recording Frankie. Debbie remembers no one being “crazy” about the song when it was first presented to them, but she said that Nile then “couldn’t get it out of his head. He did a tremendous job with it, because it was certainly different from what he [first] heard. It’s great, it’s always fun performing that song.”
