In order to reflect the rediscovery of Mârouf, le savetier du Caire, this symposium offers to highlight Henri Rabaud and his contemporaries who, overshadowed nowadays by Debussy and Ravel, were the architects of our musical modernity as well. Rabaud, d’Ollone, Ropartz, Pierné, Cras, Bruneau and many others fully deserve to be discovered anew.
