Sister Sledge is an American musical group formed in 1972 and consisting of four singers, all of whom are sisters: Kim, Debbie, Joni, and Kathy Sledge. Their biggest success came in 1979 with the popular disco anthems "We Are Family" (#1 R&B, #2 Pop in the USA) and "He's the Greatest Dancer" (#1 R&B, #9 Pop in the USA), produced by Nile Rodgers and Bernard Edwards of Chic. Both songs were included on their 8-song 1979 album We Are Family. Their followup album was 1980's Love Somebody Today, which included the songs "Got to Love Somebody" (#6 R&B and #64 Pop in the USA, #34 Pop in the UK) and "Pretty Baby". Switching to producer Narada Michael Walden in 1981, they released the album All-American Girls, yielding two hits (the title track, which reached #3 R&B and #79 Pop in the USA and #41 Pop in the UK, and "Next Time You'll Know", which reached #28 R&B in the USA). The sisters continued singing new material throughout the 1980s and 1990s. They achieved an international #1 hit with "Frankie" in 1985. Their album African Eyes was released in 1998. Their latest release is "Style" which is currently available on www.sistersledge.com.
