L’ovadese wrote “ the performance of the Serenade in C major of Tchaikovsky, under the exceptional direction of Appert, was in such a style that it brought out the elegance and grace of the melodic lines with Mozartian inspiration. …The L’Orchestra Sinfonica Citta di Grosseto…performed the Barber Adagio with rare effectiveness, emphasizing its intrinsically rich melody.” Giornale di Sicilia praised his interpretation of Nielsen’s First Symphony as "lyrical with an airy freshness" and his conducting as "precise, painstakingly accurate, and diligent.”
