Forget disco. In the ’70s, there was one hot item: groovy, raucous, and heated acid-melange riffs, usually set to rock backbeaters but, occasionally, twisted by someone a little wilder—someone like George Clinton, who punched up soul music into funk with his Parliament and Funkadelic, garnering more than 40 hit r&b singles in the process. (They were essentially the same musicians, just with different bottom lines; Parliament skewed more brass and vocals, Funkadelic more rock.) Now, George Clinton and the Parliament Funkadelic, all together again in their zany, bedecked enthusiasm, will give a long-delayed follow-up to their last major outing: onstage at the 2004 Grammys with OutKast, full brilliant absurdity flying in the wind; hope they offer up “Tear the Roof Off the Sucker (Give Up the Funk)” and “(Not Just) Knee Deep.”
