Atomic Bomb!, Meltdown Festival, review: David Byrne's supergroup light up the Southbank

Atomic Bomb! is a supergroup put together by David Byrne (who curates this year’s Meltdown Festival) after he discovered the music of William Onyeabor through his world music record label Luaka Bop. The Nigerian musician has since achieved a cult status; he very rarely grants interviews and has never performed live, yet he produced some of the most forward-thinking music of the Seventies, involving synthesisers on an epic scale.
