Though it often took a back chair to its sister group Parliament, Funkadelic furthered the notions of black rock begun by Jimi Hendrix and Sly Stone, blending elements of '60s psychedelia and blues plus the deep groove of soul and funk. The band pursued album statements of social/political commentary while Parliament stayed in the funk singles format, but Funkadelic nevertheless paralleled the more commercial artist's success, especially in the late '70s when the interplay between bands moved the Funkadelic sound closer to a unified P-Funk style.
