Capitol got on top of two ’50s fads at once by issuing an album of Sumac tackling mambo. Yma (characteristically) held nothing back, and the result was one of her more enjoyable LPs, with respectably swinging mambo grooves crafted by Billy May. “Five Bottles Mambo” is one of her most astonishing vocal workouts, dropping into guttural growls that are downright bestial, and making one wonder how exactly they got away with that in the conservative milieu of the 1950s. – Richie Unterberger
