South African piano maestro Bheki Mseleku has died at his home in London.
Mseleku, who was widely respected in jazz circles internationally, but sadly underrated at home, died a "lonely death" on Tuesday in his flat in London. His common law wife Nomvula Ndlazilwane said she had last seen him alive on Sunday.
The jazz ambassador is understood to have been ill for some time. He was diabetic.
His close friend back home, Mfana Mlambo, has lashed out at the local music industry.
"His daughter, Brenda Makhanya, has been trying to organise for him to play at home for five months. Nobody was interested. Now that he is dead everybody is interested in him," he said.
Mseleku's brother Langa Mseleku said: "His body will definitely be brought home for burial, most probably in Durban," he said.
"It is with deep sadness that we have learnt of the death of Bheki Mseleku, the internationally-renowned piano maestro," said Arts and Culture Minister Pallo Jordan.
