The 16-year-old won the admiration of two judges at the blind auditions aired on TF1 a few weeks ago with a cover of Chuck Berry’s “Johnny B. Goode,” a song which he says his mum used to play in the car during the school run.

The Swedish-French national, who plays guitar, bass, drums, keyboard and trumpet, told Delano he was amazed to get so far as “my voice isn’t my first instrument”. Faced with the prospect of joining team Jenifer or team Patrick, he opted for the latter. “He was the person I was looking for to buzz because I think he has the most interesting comments and the best advice for candidates,” Ernoult said.

Ernoult landed a place in the contest after scouts spotted him on Facebook and invited him to pre-selection trials in early 2017. A student at the European School I, he has studied guitar since the age of 6. He told Delano that he was inspired to learn to play after hearing Sheryl Crow’s “Real Gone” in the film “Cars” when he was just 4.

In recent years he has been studying jazz guitar at the Conservatoire de la Ville de Luxembourg and has played a number of concerts, some with his dad, brother and sister.

Friday will see Ernoult and two other acts perform a song chosen by the coach. The latest episode was filmed in January and Ernoult has had to keep the outcome secret ever since.

Catch the performance on TF1 at 9pm.
