Rok, besides the divas we know very well, here's somebody I like a lot, "Lorez Alexandria"; I can feel that she has lived the songs she sings. For example "The End of a Love Affair"; I've got a version she sang juxtaposed against a version by the Wes Montgomery Trio.

Now here's Wes Montgomery's instrumental;

Does the vocal help you understand the instrumental, or does the instrumental go deeper into the emotions of the the vocal?
My favorite by Lorez is "Softly As In a Morning Sunrise";

This is the MJQ doing the same tune;

When you juxtapose the vocal against the instrumental, you plumb the full meaning and emotional depth of the tune.
Enjoy the music.
