"On 13-10-1870 there was, by way of an exception, an Abonnement suspendu, the reason being that a nine year-old boy, the son of a local Jewish tradesman named Mahler, was to be heard for the first time playing the piano before a large audience. The great success the future virtuoso achieved with his audience did him honour; one could only wish that for his excellent playing he had had an equally good instrument at his service. If the young artist's former teacher, Herr Kapellmeister Viktorin, hears of yesterday's success, he can certainly be pleased with his protege."
