Sly and the Family Stone was an American band from San Francisco. Active from 1966 to 1983, the band was pivotal in the development of funk, soul, rock, and psychedelic music. The group's core line-up was led by singer-songwriter, producer, and multi-instrumentalist Sly Stone, and included Stone's brother and singer/guitarist Freddie Stone, sister and singer/keyboardist Rose Stone, trumpeter Cynthia Robinson, drummer Greg Errico, saxophonist Jerry Martini, and bassist Larry Graham. The band was the first major American rock group to have a racially integrated, male and female lineup.

In 1966, Sly Stone formed a band called Sly & the Stoners, which included acquaintance Cynthia Robinson on trumpet. Around the same time, Freddie founded a band called Freddie & the Stone Souls, which included Gregg Errico on drums, and Ronnie Crawford on saxophone. At the suggestion of Stone's friend, saxophonist Jerry Martini, Sly and Freddie combined their bands, creating Sly and the Family Stone in November 1966. At first the group was called Sly Brothers and Sisters but after their first gig at the Winchester Cathedral, a night club in Redwood City, California, they changed the name to Sly & the Family Stone. Since both Sly and Freddie were guitarists, Sly appointed Freddie the official guitarist for the Family Stone, and taught himself to play the electronic organ. Sly also recruited Larry Graham to play bass guitar.  Vanetta Stewart wanted to join the band as well. She and her friends, Mary McCreary and Elva Mouton, had a gospel group called The Heavenly Tones. Sly recruited the teenagers directly out of high school to become Little Sister, Sly and the Family Stone's background vocalists.  After a gig at the Winchester Cathedral, CBS Records executive David Kapralik signed the group to CBS's Epic Records label. The Family Stone's first album, A Whole New Thing, was released in 1967 to critical acclaim, particularly from musicians such as Mose Allison and Tony Bennett. However, the album's low sales restricted their playing venues to small clubs, and caused Clive Davis and the record label to intervene. Some musicologists believe the Abaco Dream single "Life And Death In G & A", recorded for A&M Records in 1967 and peaking at #74 in September 1969, was performed by Sly and the Family Stone.  Davis talked Sly into writing and recording a record, and he and the band reluctantly provided the single "Dance to the Music". Upon its February 1968 release, "Dance to the Music" became a widespread ground-breaking hit, and was the band's first charting single, reaching #8 on the Billboard Hot 100. Just before the release of "Dance to the Music", Rose Stone joined the group as a vocalist and a keyboardist. Rose's brothers had invited her to join the band from the beginning, but she initially had been reluctant to leave her steady job at a local record store.  The Dance to the Music album went on to decent sales, but the follow-up, Life, was not as successful commercially . In September 1968, the band embarked on its first overseas tour, to England. It was cut short after Graham was arrested for possession of marijuana and because of disagreements with concert promoters.
