Sylvester Stewart, better known by his stage name Sly Stone, is an American musician, songwriter, and record producer who is most famous for his role as frontman for Sly and the Family Stone, playing a critical role in the development of 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." Crawdaddy! has called him "the founder of progressive soul".
Born in Texas and raised in the Bay Area of Northern California, Stone mastered several instruments at an early age and performed gospel music as a child with his siblings 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.
