Cannonball Adderley was a colleague of Miles Davis in some of the early experimental projects. But his own inclinations usually kept him in the modern mainstream, and his great success as a leader had sometimes seemed to be as interesting socially as musically. “The Cannonball Adderley Quintet In Person” was the latest of a series of albums his group had recorded before night-club audiences. The recital had guest appearances by Nancy Wilson, and by Lou Rawls, a handsome blues singer. It also featured instrumentals in which there were more blue notes per four-bar phase than ever was believed possible.
