"He created another kind of rhythmic style for R&B music."
James was honored in June by the American Society of Composers, Authors and Publishers with the Rhythm & Soul Heritage Award.
The award was presented by Motown founder Berry Gordy Jr.

Neil Portnow, president of the Academy of Recording Arts and Sciences, which presents the Grammy Awards, said: "The world mourns a musician and performer of the funkiest kind.
