I have a French CBS double CD reissue combining these two LPs:
The latter included some tracks with the four backing Conte Candoloí, Gene Quill, Seldon Powell, or Jimmy Cleveland, but also some from other groups - Ronnel Bright, Ray Bryant, Sahib Shihab. Columbia recorded a number of sessions that did not produce enough material for a whole LP and ended up in such compilations.
There was a third LP:
There never was a reissue with all the material involving the Rhythm Section - the Candoli tracks are on a Fresh Sound CD with other sessions of the trumpeter.
I like the ballad tracks best - there is a nice Milt Hinton feature on "I'm Gettin' Sentimntal Over You".
I always wondered what happened to Galbraith .....
p.s. I cannot find any Donald Byrd tracks with them ...?
