Sylvester Stewart, better known by his stage name Sly Stone, was an American musician, songwriter and record producer. He was the frontman of Sly and the Family Stone, playing a critical role in the development of psychedelic soul and funk with his pioneering fusion of soul, rock, psychedelia, and gospel in the 1960s and 1970s. AllMusic stated that "James Brown may have invented funk, but Sly Stone perfected it," and credited him with "creating a series of euphoric yet politically charged records that proved a massive influence on artists of all musical and cultural backgrounds".

Born in Denton, Texas, and raised in the Bay Area city of Vallejo in Northern California, Stone mastered several instruments at an early age and performed gospel music as a child with his siblings (and future bandmates) Freddie and Rose. In the mid-1960s, he worked as both a record producer for Autumn Records and a disc jockey for San Francisco radio station KDIA. In 1966, Stone and his brother Freddie joined their bands together to form Sly and the Family Stone, a racially integrated, mixed-gender act. The group would score hits including "Dance to the Music" (1968), "Everyday People" (1968), "Thank You (Falettinme Be Mice Elf Agin)" (1969), "I Want to Take You Higher" (1969), "Family Affair" (1971), and "If You Want Me to Stay" (1973) and acclaimed albums including Stand! (1969), There's a Riot Goin' On (1971), and Fresh (1973).

By the mid-1970s, Stone's drug use and erratic behavior effectively ended the group, leaving him to record several unsuccessful solo albums. He toured or collaborated with artists such as Parliament-Funkadelic, Bobby Womack, and Jesse Johnson. In 1993, he was inducted into the Rock and Roll Hall of Fame as a member of the group. He took part in a Sly and the Family Stone tribute at the 2006 Grammy Awards, his first live performance since 1987.
