Can't really see all of the fuss being made over Natalie Cole. She's certainly competent, perhaps better than many at what she does, but, in the end, no big deal - at least to my ears.
The current state of jazz vocalizing, which Jim brought to the fore, is a more interesting subject. I'm not that well versed on jazz vocalists, current or past, but I know that others are, and I hope they'll comment -on either this or another thread.
