West Africa has been paying tribute to drummer Tony Allen, who died in Paris on 30 April. The Nigerian was considered by many – among them legendary producer and musician Brian Eno and Red Hot Chili Peppers’ bassist Flea – to be the finest drummer the world has ever seen. His fluid, polyrhythmic style behind the kit put the beat in Afrobeat as an integral part of Fela Kuti’s band Africa ‘70 and he went on to find fame – and a host of A-list collaborators – around the world.
