Nicknamed “Little Miss Dynamite” in part for how her diminutive frame packs a truly explosive voice, Brenda Lee dominated the U.S. pop charts in the '60s with chipper rockers and woozy ballads alike. Her sustained emotional delivery provides tender laments like “All Alone Am I” and “I'm Sorry” with outsized catharsis, while the much-sampled “Sweet Nothin's” showcases her throaty, rockabilly-style belting. She even smudges her squeaky-clean image with the risqué edge to “Dum Dum,” and her snappy holiday chestnut “Rockin' Around the Christmas Tree” is a perennial favorite that's been given new life in Home Alone and far beyond.
