AfroCubism is currently on tour in Europe, where this group of Malian and Cuban greats played a sold-out show at the Barbican in London on Sunday. The Arts Desk called it "one of the most transporting and life-affirming gigs of the year." The Evening Standard gave it a perfect five stars, saying: "The musical links are real and there’s a clear physical delight in throwing round the exuberant solos." Band member Toumani Diabaté gave the BBC World Service a brief tutorial on the kora and how this traditional Malian instrument worked so well with the sounds of Cuba on AfroCubism.
