I'll put RED CLAY & STRAIGHT LIFE up against anything Freddie's ever done in terms of energy and groupal unity. The rest of the CTI stuff goes into something else, and it's good for what it is, but what it is ain't loose and open small group jazz, except for KEEP YOUR SOUL TOGETHER, although by then, Freddie was well into his "star trip" trumpetisticalluraly.
T? Man, Stanley's Stanley no matter WHAT context you put him in. I happen to think quite highly of Stanley's CTI output. No, it's not the same context (contexts, actually) as the BN years, but he plays great on all of them, and the production and arrangements are impeccable. Whether or likes them or not is one thing, but if one doesn't, it's because one does not like the flavor, not because the recipe was faulty and/or poorly executed.
Milt Jackson did some of his very best leader work on CTI as well (been playing the shit outta SUNFLOWER lately). When the formual worked, it put great soloists into a different context than a blowing session, which as much as we all like that kind of thing is not the only venue for an artist to make satisfying music for either themselves or audiences. The ensemble arrangements were usually added on after the fact, so what you get is essentially the benefits of a small group record w/the "luxury" of what was more often than not interestingly written accompanying ensembles. The records had a distinct identity apart from the jazz norm. If that identity was of a populist/popular bent, oh well, and bfd.
When it worked, that is. After a while, it did get predictable, and as the label's original artists cashed in and left the label, their replacements were not as distinctive and/or didn't fit with the formula as well. But the first 2-3 years of the CTI output works just fine for me far more often than not as part of a well-balanced musical diet.
