Sly and the family Stone is an American funk, soul and rock band from San Francisco, California. Originally active from 1966 to 1983, the band was pivotal in the development of soul, funk, and psychedelic music. Headed by singer, songwriter, record producer, and multi-instrumentalist Sly Stone and containing several of his family members and friends, the band was the first major American rock band to have an integrated lineup in both race and gender.
Brothers Sly and singer/guitarist Freddie Stone combined their bands (Sly & the Stoners and Freddie & the Stone Souls) at the end of 1966. Sly and Freddie Stone, trumpeter Cynthia Robinson, drummer Gregg Errico, saxophonist Jerry Martini, and bassist Larry Graham completed the original lineup; Sly and Freddie’s sister, singer/keyboardist Rose Stone, joined within a year. This collective recorded five Top 10 hits and four groundbreaking albums, which greatly influenced the sound of American pop music, soul, R&B, funk, and hip-hop music. During the early 1970s, the band switched to a grittier funk sound, which was as influential on the music industry as their earlier work.
