Sister Sledge is a renowned American vocal group from Philadelphia, formed in 1971 by sisters Joni, Kim, Debbie, and Kathy Sledge. Rising to fame during the disco era, they became global stars with their album We Are Family in 1979, featuring the classic hits He's the Greatest Dancer and We Are Family. The group is known for their soulful harmonies and energetic performances, earning a Grammy nomination for their signature sound. Over the years, their music catalog expanded with songs like My Guy, Mama Never Told Me, Thinking of You, and the UK chart-topping Frankie in 1985. Despite individual ventures, especially Kathy's solo career, the sisters have continued to perform on various stages, making memorable appearances such as their 2015 show for Pope Francis. As of 2024, Sister Sledge splits into two touring acts, with Debbie leading Sister Sledge featuring Sledgendary alongside family members, and Kathy fronting Sister Sledge featuring Kathy Sledge with special guest artists. The group's enduring legacy is marked by their anthems of unity and timeless dancefloor appeal.
