Originally known as one-half of reggaetón duo Arcángel & De La Ghetto, Rafael Castillo went solo in 2008, and he's been enchanting fans with his cool mix of seduction and aggression ever since. “Acércate” drips in pre-coital sweat and gets rowdy over infectious dembow rhythms; electro-trap brilliance sets the mood on “La Ocasión,” where the suave rapper reminisces about past conquests. While “Exitandonos” details explicit private-quarter activities, the confessional “Es Difícil” charmingly reveals his yearning heart.
