Lortie expects to recover fully, the representative emphasized.

Tonight's performance, at Stanford University's Dinkelspiel Auditorium, was to include solo works by Schubert, Liszt, Berlioz, and Ravel.

According to the Portland Oregonian, Oregon Symphony executives learned on October 3 at 6 p.m. that Lortie would not be able to perform Rachmaninoff's virtuosic Third Piano Concerto either at that night's concert or the following evening.

After a hurried conference, orchestra officials and musicians decided to substitute Tchaikovsky's Fourth Symphony for the concerto at Sunday's concert. Meanwhile, artistic administrator Charles Calmer began searching for a pianist to perform the "Rach 3" on Monday.

At noon on Monday, pianist Yakov Kasman, a faculty member at the University of Alabama in Birmingham, agreed to step in, and rushed to make a plane that would get him to Portland an hour before the concert. After seven minutes of rehearsal and a brief discussion with conductor Carlos Kalmar, Kasman performed the famously difficult solo part to an enthusiastic reception, the Oregonian says.
