Totally agree with Orpheus and Frogman's comments on Ella. Simply the best jazz vocalist for me, hands down. Knows exactly when to scat and when not to, and does it with the technique of an instrumentalist.
Speaking of singers with the technique of instrumentalists, if some of you jazz fans are curious about checking out some opera singers, try Marilyn Horne. Stunning technique, and an incredible range, and a wonderful voice, though for some of you her vibrato might take some getting used to. A great intro, which also happens to be an incredible recording as far as quality goes as well, is the recording she did of Carmen at the Met with Leonard Bernstein in the 70s on the Deutsche Gramophone label. It's a great intro to opera, and you will recognize a few of the tunes. For some sheer vocal pyrotechnics, check out some of her recordings of Rossini and Handel arias.
