On these brilliant regional Mexican rarities, Jenni Rivera diversifies her norteño portfolio. She drops sassy puns on ranchera jams like the playful “Tequilera” and lets her bewitching, smoky coo smolder on the mariachi tune “Ni Princesa Ni Esclava” (Neither Princess Nor Slave). The oldie-but-a-goodie cover of “Angel Baby” goes the tuba route in her daring, experimental hands.
