Well, speaking broadly of all the Verves, certainly these with Clark are excellent:
Jazz Tones
In A Mellow Tone
Odalisque
Autumn Leaves
Cooking The Blues
Sweet and Lovely
I have the Mosaic set in each format (have tried to sell the LP but I guess I'm fated to keep it) and this is great music, and the individual Japanese cds I have heard sound equally good if a bit different than the Mosaic mastering.
I do like the others, each has its charm, but I would say those above may have just a shade more interest as Clark plays very very well on them.
