Rose Stone (or Rosie Stone) (born Rosemary Stewart, March 21, 1945, in Vallejo, California) is an African-American singer and keyboardist. She is best known as one of the lead singers in Sly and the Family Stone, a popular psychedelic soul/funk band founded by her brothers, Sly Stone and Freddie Stone. She often wore a platinum-colored wig while performing with the band, and was noted for her strong vocals.
After the band's dissolution in 1975, "Sister Rose" (as she was also known) married Sly Stone's former manager/co-producer, Bubba Banks. She later recorded a solo album on Motown Records, billed as 'Rose Banks'. During the 1980s and 1990s, Stone worked as a backing session singer, appearing on recordings by Michael Jackson, Phish, Ringo Starr, Reef and Bobbysocks!. Stone is today part of the musical department at her brother Freddie's church. She returned to her gospel roots in 1983 when she sang on Sandra Crouch's Grammy Award-winning album We Sing Praises, soloing on the old hymn "Power in the Blood". She has been associated with the Crouch family and the music department of Christ Memorial COGIC in California for many years.
