Rudolf Barshai (1924-2010)
Rudolf Barshai, the Russian-émigré violist and conductor for whom Dmitri Shostakovich wrote his last work, the Viola Sonata (1975), has died in Switzerland at the age of 86.
Barshai was perhaps best-known for his string-orchestra version of Shostakovich's Quartet No. 8, known as the Chamber Symphony, Op. 110a. Barshai also produced a highly regarded completion of Mahler's Tenth Symphony and an arrangement of Bach's "Art of the Fugue," finished shortly before his death.
He was a founding member of the Borodin Quartet in 1945, and in 1955 founded the Moscow Chamber Orchestra. After leaving the old Soviet Union in 1975, he conducted widely in Western Europe.
