Black Rhythm Revolution! Is the first solo album from the jazz-funk legend Idris Muhammad, a New Orleans-bred rhythm king who successfully made the leap from the finest soulful jazz records of the ’60s to the nastiest fusion funk of the ’70s. Here we catch him literally on the cusp of the two in 1970, with one good foot in the get-down of “Express Yourself” and “Super Bad,” and the other in his own heady excursions into modal rhythm and melody, accompanied by virtuosos Kenny Barron, Ron Carter, Melvin Sparks, who came together for sessions overseen by legendary producer Rudy Van Gelder.
