French singer Barbara Weldens died on Wednesday on the stage of a festival in southwest France, French media reported on Thursday.

Weldens, 35, had been performing in a church as part of the Leo Ferre festival in the picturesque village of Goudron, in the southwestern Lot region, before collapsing suddenly due to an apparent electrocution, Europe 1 radio reported on Thursday.

When rescue services arrived, she was already in cardio-respiratory arrest and could not be saved.

Local police have opened an inquiry to determine the cause and circumstances of her death.

In 2016, Weldens won first prize in the Jacques Brel Young Talents contest. On Feb. 3, she released her first studio album, Le grand H de l'homme.
