Maybe Blue Note was trying, but the musicians didn't seem to be co-operating  
 
One interesting thing about Soul Jazz is that the musicians have all sorts of different backgrounds: Swing; Blues; R&B; Soul; Funk; Gospel; Bebop; Hard Bop. And they bring different ideas from these other kinds of music. 
 
For example, Baby Face Willette's albums were quite different to Fred Jackson's, even though Jackson was on one of Willette's. And both were quite different from Ike Quebec's albums with Freddie Roach, which were quite different from Roach's own albums. And all of this was different from what Lou Donaldson was doing with Willette and Patton. And different from what Patton was doing as a leader. And Don Wilkerson was different, and so was Harold Vick. And all of this with some of the same people - like Grant Green and Ben Dixon - running through many of the albums. (And this is just to think about Blue Note. When you add in Prestige - with people like Jaws/Scott; Arnett; Jug; Red Holloway; J H Smith; Forrest - and Riverside - with people like Johnny Lytle and Cannonball/Nat - Argo - with Ramsey Lewis & Al Grey - and PJ, with McCann, Holmes etc etc... Then add in vocalists like Della Reese, Nancy Wilson, Etta Jones, Lou Rawls.) 
 
Because Soul Jazz probably isn't one thing; it could probably be thought of as an umbrella term covering a multitude of different styles with, as their only (or at least main) common denominator, their orientation towards the popular black market.
