Born in 1960 in Neuilly-sur-Seine (France), Alain Celo eventually devoted himself to music after completing his high-school diploma with a major in sciences, and winning a First Prize at a national-level school competition in music (1978).

He is selected to join the Orchestre National de Metz in 1986, and has worked there since then.

Settled in Metz, he enrolls at the music school where he attends harmony, counterpoint, fugue, orchestration classes and received a Golden Medal in each of these matters.

He is part of François Narboni's composition class and ends his studies with a First Prize in the advanced class and the SACEM Prize. Advises were also given to him by Claude Lefebvre, George Crumb and Martin Matalon.

Mainly inspired by the relationship between man and nature, his research aims at creating a homogeneous language with heterogeneous elements, thus offering some aesthetic similarities with Mahler's work. He admits to being influenced by Ravel, Debussy and Stravinsky, but also jazz and ethnic traditional music.

The Orchestre National de Metz, United instruments of Lucilin, Souffle d'Ebène, Trio KDM, Ensemble Stravinsky and Pittsburgh New Music Ensemble are among the ensembles that have interpreted his pieces up to this day.
