La Arrolladora have always spiced their expansive albums with body-moving cumbias, but they fully embrace that bewitching rhythm on Calidad Y Cantidad. Whether they're furiously working up a sweat or simmering at cheek-to-cheek tempos, the legendary banda ensemble's percussionists nearly outshine the sizzling brass and soulful vocalists on grooves like "Tú Eres La Razón" and "Me Lastimaste." And while the album still regularly departs from the dance floor, those same exhilarating drums push the stately corridos ("Calidad Y Cantidad") and sorrowful ballads ("Mi Sigue Haciendo Daño") toward their heart-swelling crescendos.
