Pharaoh Sanders has many high-points in his illustrious career, but Black Unity is a truly special, long-form body of work stretching out over 37 minutes of mesmerising, sustained groove. Widely hailed by critics as one of Sanders' most revealing works, he's joined on the 1971 session by Marvin Peterson on trumpet, Carlos Garnett on flute and tenor sax, Joe Bonner on piano, Stanley Clarke and Cecil McBee on bass, Norman Connors and Billy Hart on drums and Lawrence Killian on percussion. Between them, the ensemble guide us through ebbs and flows of majestic power, all elements flowing into one another in a true expression of the unity Sanders spelt out in the title.
