​On September 13, 2025, Akis Kalmoukis joined the Mantzaros Philharmonic Society and the Ensemble of Winds performing a grand concert at the Duomo of Napoli, a majestic 13th-century monument. Alongside distinguished soloists and orchestras, Akis delivered stirring performances of Neapolitan, Italian, Ionian, and Greek repertoire. His appearances as a tenor added a lyrical thread through the evening’s diverse program, bridging cultural heritage and operatic artistry. Supported by the young Neapolitan orchestra Sanitansemble and under the baton of Paolo Acunzo & Socratis Anthis, the concert also carried strong social resonance, strengthening ties between cultures and showcasing music as a force of unity.
