[1][3] In 1905 he returned to Haiti, where he met his colleague Ludovic Lamothe, composer and musician like himself, with which he will play and make a tour of major cities.
Ludovic Lamothe drew from African roots to express the meringue, while Justin Elie instead turned to the Amerindian past of Saint-Domingue.
