Though The Fun Ones largely emphasizes modern funk and instrumental music, RJ still occasionally flirts with vocal stylings across the album. On "One Of A Kind," RJ links up with Homeboy Sandman, pushing the levels of syncopation into the red. "A Genuine Gentleman" sees RJ and the king of west coast abstract rhyming, Aceyalone, reuniting on record for the first time since 2006 over a Meter's-esque groove. Longtime Rjd2 collaborators, STS and Khari Mateen, reconvene on lead single, "Pull Up On Love," to bring the spirit of James Brown to the quintessential Atlanta rib shack. Jordan Brown steps in to bring a falsetto lilt over a cacophonous drum break that would leave Ginger Baker scratching his chin.
