Banda and duranguense have always seemed like long shots for breaking Mexican regional into the pop mainstream. And yet the oompah-ing horns and synth beats of these genres share a common ground with the dance beats of the pop charts -- and Jazmin Lopez may have homed in on it. Jazmin is ebullient and infectious, like both good banda and good dance pop are. But like her paradigm-challenging predecessor Yolanda Perez, the savvy Ms. Lopez also manages to work in more mainstream pop elements, intertwining her husky "Oo! Oo!"s and throaty vocals with R&B flourishes ("La Carcacha") and hip-hop beats ("Tu").
