This Friday, May 24, Slimane sang in concert at the Forest National in Brussels. He had a nice surprise in store for the spectators present. During the show, he started singing “I am sick” by Serge Lama. After a few measurements, he stopped and turned around. The surprise was big since it was Lara Fabian who joined the singer to continue in front of a delighted audience. The two artists then mixed their voices with intensity, even performing, like Slimane at Eurovision, an a cappella passage.
