Born in Egypt, Eidi did his first musical studies at the Beirut Conservatory (in the classes of Zafer Dabaghi and Leila Aouad), where he graduated at fifteen.
In his concerts throughout the world (France, England, Italy, Switzerland, Belgium, Spain, Germany, Luxembourg, Czech Republic, Greece, Bulgaria, Ukraine, Sweden, United States, Japan, South Korea and the Middle East), he particularly defends the romantic repertoire and the French music of the twentieth century, striving to discover unknown authors and repertoires.
Eidi has created pieces by Erik Satie (Sixième Nocturne), Henri Sauguet (Ombres sur Venise which is dedicated to him), Maurice Jaubert, Guy Sacre, Narcís Bonet [fr], Karol Beffa...
These tastes and these concerns are to be found in his records, to this day about fifteen, of which many premières: as well works for piano (Sauguet, Milhaud, Scriabine, Sacre, Satie, Poulenc, Séverac) as melodies (Ravel, Debussy, Poulenc, Auric, Honegger, Chausson, Delage, Sacre), Albert Roussel's complete work, with Marie Devellereau, Yann Beuron and Laurent Naouri.
He is regularly invited for master classes, both in France and abroad (notably in Spain, China, Japan and South Korea).
