Over 500 musicians from all over Africa had entered in the competition.
The RFI Discovery Award is organised in partnership with CulturesFrance, the French Ministry of European and Foreign Affairs and the Organisation Internationale de la Francophonie.
Kirya wins the prize money plus a grant worth 18,000 euros to develop his career and will stage performances in Paris plus a year-long tour of Africa.
