His elevated interest in contemporary music led him to the foundation, together with the stage director Giorgos Michaelides, of the
Opera Workshop in 1989, that offered him the opportunity to conduct several musical stage works. Tsouchlos has conducted a considerable number of first performances of Greek works (by such composers as Antoniou, Adamis, Vrondos, Risiotes, Mikroutsikos, Zannas, Koumendakes, Metalinos, etc.). He appeared as a guest conductor with various orchestras and artistic institutions, in Greece as well as abroad (France, Germany, Austria, the Czech Republic, Italy, Mexico). He is Director of the Artistic Programming of the
Athens Concert Hall since 1991.
