I agree all the aformention tracks have good arrangements. But just about everything arranged by McKinley Jackson from the early 70's until the late leaves most in his wake, and I do say most, not all. Listen to Popcorn Wylie's, ESP LP or his work at ABC with Bobby Hutton, Reggie Garner, Lamont Dozier to name a few. Even lovers of the 60's when listening to this would have to agree that he moved the benchmark. The Holland brothers to this day, still ring him to consult on arrangements.
