The go-to tunes for this Marseille rapper reveal much about his cosmopolitan style. Rubén Blades’ Caribbean disco funk and Bitty McLean’s rocksteady get in step with the rootsy soul of Fertile Ground and Cody ChesnuTT. Tracing filigrees between them is Ali Farka Touré and Boubacar Traoré‘s desert blues, while Billie Holiday’s “Strange Fruit” and Omara Portuondo reflect Reef’s bittersweet edge.
