Along with James Brown and Parliament-Funkadelic, Sly and the Family Stone were pioneers of late 1960s and early '70s funk. Their fusion of R&B rhythms, infectious melodies, and psychedelia created a new pop/soul/rock hybrid, the impact of which has proven lasting and widespread. Motown producer Norman Whitfield, for example, patterned the label's forays into harder-driving, socially relevant material (such as The Temptations' "Runaway Child" and "Ball of Confusion") based on their sound. The pioneering precedent of Stone's racial, sexual, and stylistic mix, had a major influence in the 1980s on artists such as Prince and Rick James. Legions of artists from the 1990s forward – including Public Enemy, Fatboy Slim, Beck, Beastie Boys and LL Cool J's popular "Mama Said Knock You Out" along with many others – mined Stone's seminal back catalog for hook-laden samples.
