I've several of her albums, and tonight, I dug up one of her albums and played it:
This is one of her best work, as it turned out (for me). It has the most balanced recording, rich in details and nuances of the band, her vocalese repertoire and inflections convey the emotions.
Well, enough superlatives, if you are into Jazz vocal standards, this is one of the album that you can use to showcase your speakers. Lots of nuances that I am sure you can appreciate.
(it was recorded back in '98-'99)
