On the heels of Tijuana's Julieta Venegas alt-pop smash hit and Latin Grammy winner Sí comes yet another Mexican norteña that should make as much noise. Monterrey-born Ely Guerra's fourth album is truthful to its name. It has a strong pop element during the "sweet and sour" segment (the first six songs); and as delicate, ethereal, and sensual as you can get in a country as machista as Mexico when she shows off her "hot and spicy" sides. At 32, Guerra finally understands that beauty does not go against quality. Long enough time for her audience to understand it, too.
