Sly Stone, American musician and record producer (died 2025)

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". Crawdaddy! has credited him as the founder of the "progressive soul" movement.
