Anita O’Day once again proves herself all too multifaceted on this 1956 album, casually mastering enough divergent modes to make most other jazz singers green with envy. She brings a torchy throatiness to Irving Berlin’s vibraphone-kissed ballad of romantic awakening, “I Used to Be Color Blind,” while her bluesy drawl establishes an unshakeable gravity on the daringly stripped-back “Sweet Georgia Brown.” But then she’s back to swinging, winking pep for “Stompin’ at the Savoy,” a horn-guided showcase of her breezy yet flavorful phrasing.
