John Legend and the Roots' ?uestlove recently stopped by the Rolling Stone offices to preview their upcoming "gritty and raw" soul collaboration Wake Up! . The LP features Legend and the Roots adding some funk flavor to socially conscious songs by soul legends like Donny Hathaway, Bill Withers and Marvin Gaye while putting a modern twist to obscure cuts like Baby Huey and the Babysitters' "Hard Times," with ?uestlove calling their rendition "the funkiest song ever created in the last 10 years."
