Faced with ecological disaster and government inaction, El Gato Negro rings the alarm with its fourth single "La Vague". The rhythm rumbles, the brass section blows a disquieting jazz, the lyrics hit to the guts while the voice of the Senegalese singer Nafi Gawlo tears the sky. "Danse une dernière fois, serre moi mon amour" (Dance one last time, hold me close, my love) are Axel's last words on this track, which will close his new album.
