She started out as one of Stan Kenton's singers, after Anita O'Day and after (I think) Chris Conner. Vocally, I think she is kind of similar to Chris Conner. Her voice has both a dark timbre but also has a bounce and conveys a sense of lightness, if that makes sense. Her best albums were done for Capitol (after Kenton) with arrangements by THEE GREAT PETE RUGOLO. I would start with either "Something Cool," "Gone for the Day" or "The Misty Miss Christy." If you get "Something Cool," be sure you're getting the original mono (the stereo was a re-record). Avoid her volume in the Capitol "Great Ladies of Song" series. It focuses too much on ballads and is not a good representation of her style overall, IMHO.
