I never found myself mistaking Sarah Vaughan's voice for a man's, but to each his own. The Ellington Songbooks are among my favorite Vaughan performances, and my collection of Sarah is fairly complete. She does a wonderful job on every tune. Six more performances, especially if they are new tunes and not just other takes of older ones, would be very attractive, but for my money, this is very, very fine "late" Sarah.
