Being lazy, one might dismiss Baltimore’s Spank Rock as a sweltering East Coast riff on Dizee Rascal. Squelchy beats, blink-and-they’re-over samples and front-man Naeem Juwan’s frenetic delivery mark this out as hip hop unabashedly of the left-field. Then the chorus, a looping girly-girl chant that burbles like a waterfall kicks in and you forget these guys are pure hipster bait. Marvelous, despite itself.
