Let's be real: smoothness and delicacy aren't the first qualities you'd expect from a rapper who calls himself Bone Crusher, and who built his name on high-energy club music. Surprisingly, though, the Vibrations the Southern veteran produces on this new promo single (his first solo feature since '07's Transform) aren't the type that would register on a seismograph. On the contrary, this joint's vibe is downright chill and seductive. Over Nitto's airy, string-laced production, the rhymesayer busts out his suavest bars, underscoring the sensual mood by dragging out the final syllable of each line. A silky chorus and guest verse from DMV crooner Raheem DeVaughn round out the package. Feeling it? Vibrations isn't slated to appear on any forthcoming project, but we'll keep you posted on Bone Crusher's plans as futher details emerge.
