Clarence Greenwood, aka Citizen Cope, was born in Memphis, but his folk-pop/blues/hip-hop/reggae/soul sound is as much influenced by his days in the D.C. area, where he once DJ’ed with Basehead. Though he seemingly fits into the laid-back Jack Johnson/G. Love surfer-slacker mold (not to say anyone’s slacking; it’s just a vibe), he might beg to differ. He’s big on building rhythms and letting lyrics braid around them in sometimes hypnotic waves of repetition, and songs like “Brother Lee” express a social conscience that’s never far from the surface of his work. Though he’s been on (and off) four major labels in his approximately 12-year recording career, he’s got a relatively small discography. Fans have been waiting for another release since 2006’s Every Waking Moment. But even without new releases, Citizen Cope shows are an easy sellout regardless of where he plays — whether he’s doing an intimate solo gig or a larger venue like Stubb’s, where his February appearance left plenty of ticketless fans begging.
