"Angelo Mariani was considered at that time the prince director, the genius director! The Italian orchestra, under him, had in fact transformed. Before Mariani, the conductors, even the most talented, had limited themselves to obtaining accuracy, balance, intonation from the orchestra, i.e. the qualities indispensable for a good performance. With him the orchestra suddenly elevated itself to the mission of interpreter, of true collaborator of the author's thoughts and feelings. (Gino Monaldi)"
