"I'm Jack Johnson, heavyweight champion of the world. I'm black. They never let me forget it. I'm black all right. I'll never let them forget it." Motifs appropriated from James Brown and Sly Stone. Teo Macero marshals Herbie into the studio after the keyboardist had made a grocery run on East 30th Street and stopped by not expecting to work. Awaiting their bandleader, John McLaughlin, Billy Cobham, and 19-year-old bassist Michael Henderson commence to jamming. Chord changes go out the window. Funk noir grooves abound. Macero pastes it all together, including snippets from In A Silent Way (1969). Miles had warned that he would make the greatest jazz rock album ever, and to my ears, he certainly delivered on A Tribute to Jack Johnson (1971).
