Thanks for posting.
A couple of thoughts:
I completely agree with your opinion of CTI between 1970 and 1974, although I am not fond of Bob James. But any of these albums from that period with either Deodato or Don Sebesky contributions are very worthwhile. I associate the 1974 cutoff date with the arrival of disco in late 1974, not that I'm knocking disco, but that early-70s introspective, urban, minor-key, black-consciousness aesthetic was largely traded in for a forget-your-troubles-and-shake-your-booty ethos.
The cultural shifts at around 1974/75 are fascinating. Disco arrived in a big way. Jaws created a new paradigm for the summer blockbuster film. Ennio Morricone stopped working with Bruno Nicolai, marking the end of Morricone's great period.
When discussing Creed Taylor, don't forget his early work at ABC/Paramount, in particular with the great and underrated Kenyon Hopkins. These albums were released under Creed Taylor's name for contractual reasons. They include The Sound of New York; Lonelyville; and the trilogy of Shock, Panic, and Nightmare.
