AFAIK, THE COOL WORLD soundtrack is still available on CD. Worth picking up.
Three OJCs that I think fit the mode of the original request...
Gil Melle, GIL'S GUESTS (which include Art Farmer, Kenny Dorham, Julius Watkins, and Hal McKusick)
Duane Tatro, JAZZ FOR MODERNS (includes the original "version" of "Maybe Next Year", one of the stand-out tracks from Art Pepper's SMACK-UP LP)
Oliver Nelson, NOCTURNE
