Graf, the music director of the Houston Symphony, will replace Sawallisch in concerts March 23-28. Dvoršk's Othello Overture replaces the composer's Wood Dove; the remainder of the program, which includes Britten's Sinfonia da Requiem and Brahms' Piano Concerto No. 1, is unchanged.
Milanov, the Philadelphia Orchestra's associate conductor, will lead the orchestra March 30-April 4 in a program featuring Brahms' Symphony No. 1 and Joachim's Violin Concerto ("Hungarian"), with Christian Tetzlaff as soloist. The program is unchanged.
Herbert Blomstedt, the former music director of the San Francisco Symphony, will conduct concerts April 6-8. Garrick Ohlsson is the pianist. An updated version of the program, which previously included works by Schubert, Haydn, and Bart‹k, has not yet been released.
