Barbara Weldens, an upcoming French singer, has collapsed and died while performing in a concert at a festival, BBC reports.
It is uncertain what caused her death, but a report said she died due to electrocution.
Aged 35, she had been on stage in a church in the village of Goudron, in the Lot region of the south-west when she suffered an apparent cardiac arrest.
She had released her first album this year and had won a young talent award.
Police have started investigating the cause of her death and have refused to speculate on the circumstances.
