This stemmed mainly from his desire to protect his students from the undue wrath of critics. For instance, he wrote Johann von Herbeck, then director of the Vienna Philharmonic, "In case [pianist Hans von] Bülow should make his appearance at the Philharmonic concert he will, on my advice, not play my A-major Concerto (nor any other composition of "mine") but just simply one of the Bach or Beethoven concertos. My close friends know perfectly well that it is not my desire to push myself into any concert programme whatever." This cautiousness was not always a hard-and-fast rule. The then-17-year-old Karl Tausig played the work in Prague on March 11, 1858. Tausig repeated it in Weimar on August 8, 1860 to general acclaim. This was after the incident in that city over Peter Cornelius's "The Barber of Baghdad" and not long before Liszt would resign as music director there.
