Just a day after the Boston Symphony Orchestra announced that its new music director designate, Andris Nelsons, was hospitalized with a concussion in Germany and would be unable to lead the Verdi Requiem at Tanglewood on Saturday evening, the orchestra has announced two more cancellations. The conductor and pianist Christoph Eschenbach has bowed out of his Friday evening and Sunday afternoon performances because of an ear infection that has made it impossible for him to travel. And the bass Ferruccio Furlanetto, who was to have sung in the Verdi concert that Mr. Nelsons was to have led, has dropped out of the roster because of a bad cold.
The shows, however, will go on. The conductor Edo de Waart will step in to conduct Mr. Eschenbachâs Friday evening concert. Mr. Eschenbach was also to have been the soloist in Mozartâs Piano Concerto No. 12 in A (K. 414), but Mr. de Waart was not prepared to fill in for him in that capacity. Instead, the pianist Garrick Ohlsson, who was already scheduled to perform on Sunday, will be the soloist in the decidedly grander Piano Concerto No. 27 in B-flat (K. 595).
The bass-baritone Eric Owens will take Mr. Furlanettoâs place in the Verdi Requiem on Saturday evening. And Carlo Montanaro will conduct the Sunday afternoon program, with Mr. Ohlsson as the soloist in the Prokofiev Piano Concerto No. 3.
