There are nearly 80 of them on stage. Strings, woodwinds, brass, percussion, choirs, grouped around the conductor, masterful and imperious. Bastien Stil directs and coordinates the ensemble with a masterful hand. He impresses with his precision and rigor. Baton in hand, his arms draw impetuous volutes in the air. His whole body is animated with ardor and passion. The musicians follow his graceful arabesques and execute with mastery the pieces chosen for the evening. It is remarkable.
