orpheus10,
I'm glad you liked the "Unreleased Art". There are 10 volumes and some of them have multiple discs "Blues For The Fisherman" has 4 discs and all 4 are outstanding.
There is another 6 volume series titled "West Coast Sessions" with many great musicians on them including Sonny Stitt, Shelly Manne, and Jack Sheldon to name a few.

Although unawares until today that Cannonball and Stan had recorded with string orchestra's, Being an Art Pepper completist I have his session with a string orchestra its called "Winter Moon" and it is a really good session. This song off of Winter Moon is another that he wrote for Laurie Pepper:
