Used to be that a Western pop singer could pilfer from Third World sounds and never think twice about the source material. Just check the tangled copyright issues surrounding The Lion Sleeps Tonight for proof. But in 2008, that tradition got flipped, when The Very Best a trio comprised of production duo Radioclit and Malawian singer Esau Mwamwaya dropped the mixtape Esau Mwamwaya and Radioclit Are the Very Best. (You can download the tape for free here.) The unofficial release found Mwamwaya singing over tracks copped from underground stalwarts such as M.I.A. and Vampire Weekend, two artists who repay the compliment by delivering great guest turns on The Very Bests official debut, Warm Heart of Africa (Green Owl).
