Well I have that Hollywood Allstar Session box too (Stitt on disc 3 & 4) beside my other Atlas series Items. All I can say and do agree there are no weak recordings in that modern West Coast series.
If Laurie sees it different you know "de gustibus non est disputandum".
The tracks on Atlas LA27-1004 "Groovin'n High" are the same as in the 5 CD. box .
My copy has a different front picture and has only 6 tracks. Sound quality is excellent on both.
