Sly and the Family Stone took the Sixties ideal of a generation coming together and turned it into deeply groove-driven music. Rock's first integrated, multi-gender band became funky Pied Pipers to the Woodstock Generation, synthesizing rock, soul, R&B, funk and psychedelia into danceable, message-laden, high-energy music. In promoting their gospel of tolerance and celebration of differences, Sly and the Family Stone brought disparate audiences together during the latter half of the Sixties. The group's greatest triumph came at the Woodstock Festival in August 1969. During their unforgettable nighttime set, leader Sly Stone initiated a fevered call-and-response with the audience of 400,000+ during an electrifying version of "I Want to Take You Higher."
