Jazz vocalists recorded wonderfully

Just arrived today, Jacintha/Lush Life a  2001 release, Specifically jazzy slow blues, 
All star back up artists, with all piano and string arraingments by  the incredibly gifted, creative Bill Cunliffe, Stunning arraignments,  Guitarist Anthony Wilson, another super star, Accordion work on a  few tracks from Frankie Marocco, 
Super Star band.
So after listening first time, all tracks have the same blues-jazzy ambience. You might think, , maybe a  change up on a  few tracks would have added some spices, 
Not really, Not a dull track on the cd. 
Following up my previous topic, , which jazz vocalists do you feel, actually work just fine, if not perfect, in spite of any studio tinkerings. 
My vote has to go with Jacintha's Lush Life. 
How much tinkering is added, is not at all important, Jacintha set out to create a  lush dreamy atmposphere, and she has acomplished the task with  wonderful success. 
Its dreamy lushness. 
Here, one never gives any thoughts about how her voice <<might be>> modded
, as she sounds just so natural  in these soft , delicate, <no rush> melodies.
This is a  2001 record, same  years as Diana Krall's releases, and Lush Life also has that warm recorded studio sound. But not nearly as warmed over as noted in Diana Krall's work.
Other artists that you consider a  natural, and not  touched up with excess.
