Popular South African musician Jabu Khanyile, who performed at the Johannesburg Live 8 concert, has died.
Khanyile had performed with Youssou N'Dour and Papa Wemba
The Afro-Jazz vocalist died on Saturday night after being admitted to hospital in the South African capital, reported the country's state broadcaster SABC.
The cause of death is not yet known, but the report said Khanyile had been in and out of hospital with diabetes.
The Soweto-born singer achieved fame with the band Bayete and was known for his colourful Masai costume.
He joined Bayete as a drummer in the mid-1980s, but soon took over as the lead vocalist, scoring hits with songs such as Mbube and Mbombela, a cover of a Miriam Makeba song.
The group disbanded in 1993, and Khanyile went on to have a successful solo career.
His first solo album, The Prince, won him a best artist prize at the All Africa Music Awards, known as the Kora Awards, in 2000.
Khanyile was a strong defender of African music on the international stage, and played with other musicians from the continent such as Youssou N'Dour and Papa Wemba.
In the run-up to Live 8, he said Westerners should hear about Africa's problems "from the horse's mouth, rather than have their own people talk for us".
"We are the ones who can spread the message with passion," he said.
His death comes soon after one of South Africa's best-loved music stars, Lebo Mathosa, was killed in a car crash.
