Under the direction of the conductor Jakob Lehmann, the celebrated original sound orchestra Les Siècles will present two symphonies that were left unfinished at this An.Ton.Hören school concert for the 14+ age group.

Firstly, Anton Bruckner's 'Ninth', which he initially did not really want to begin composing, as he confessed to his pupil Josef Gruber: "I' mag dö Neunte gar nöt anfangen, i' trau mi' nöt, because', he said solemnly continuing in written German, 'Beethoven also brought his life to a close with the Ninth'." Bruckner left his work as a three-movement fragment, although there were nine years between the start of work on it and his death, during which he was partly occupied with revising his other symphonies. On the other hand, Franz Schubert's Symphony No. 7 in B minor can be heard, of which he only completed the first two movements. He abandoned work on the third movement after just a few bars for unknown reasons. Ludwig van Beethoven was also Schubert's great role model. It is therefore quite possible that he did not complete his symphony, which became famous as the "Unfinished", because he feared that it would not fulfil his own expectations and would not stand up to comparison with the works of his idol.
