Miguel Harth-Bedoya leads two programs - one featuring Nadja Salerno-Sonnenberg in Tchaikovsky's Violin Concerto, and the other featuring Yo-Yo Ma in Shostakovich's Cello Concerto No. 1. PROGRAM NOTE 10/20: Mstislav Rostropovich has unfortunately cancelled his Shostakovich Centennial concerts, in order to undergo medical tests and evaluations. Most of the artists and repertoire originally scheduled for these concerts have been changed, with the hope that Maestro Rostropovich will lead these programs in a future season. However, Yo-Yo Ma will still appear in the Nov. 11 concert.
