Like so many Russian musicians, Mravinsky seemed first headed toward a career in the sciences. He studied biology at St. Petersburg University, but had to quit in 1920 after his father's death. To support himself, he signed on with the Imperial Ballet as a rehearsal pianist. In 1923, he finally enrolled in the Leningrad Conservatory, where he studied composition with Vladimir Shcherbachov and conducting with Alexander Gauk and Nikolai Malko. He graduated in 1931, and left his Imperial Ballet job to become a musical assistant and ballet conductor at the Bolshoi Opera from 1931 to 1937, with a stint at the Kirov from 1934. Mravinsky gave up these posts in 1938, after winning first prize in the All-Union Conductors' Competition in Moscow, to become principal conductor of the Leningrad Philharmonic. He remained there until his death, long ignoring many guest-conducting offers from abroad. Under Mravinsky's direction the Leningrad Philharmonic came to be regarded as one of the finest orchestras in the world, although the world had comparatively few opportunities to hear it aside from the rare tour (about 30 performances in 25 years, starting in 1956), some dim Soviet recordings, and a very few highly acclaimed records for such Western European companies as Deutsche Grammophon and, in the end, Erato. Mravinsky was made People's Artist of the U.S.S.R. in 1954, and in 1973, he received the order of Hero of Socialist Labor. But his more lasting international acclaim came for his performances of Mozart, Beethoven, Bruckner, Wagner, Sibelius, Bartók, Stravinsky, and anything Russian or Soviet. His reputation only rose upon his retirement from the Leningrad Philharmonic, particularly with the posthumous release in 1995 by Melodiya and BMG Classics of 20 CDs surveying Mravinsky's work from the 1940s into the 1980s.
Mravinsky's rehearsal manner was said to be autocratic and brutal, and the resulting performances were tightly clenched. Yet they were also technically precise, finely detailed, subtly colored, and highly dramatic -- and this not always because he was in the habit of whipping fast finales into a frenzy. His readings had an intensity, concentration, and -- despite the arduous rehearsal -- spontaneity comparable to those of Wilhelm Furtwängler. In the West, Mravinsky was particularly noted as an interpreter of Shostakovich, whose Fifth, Sixth, Eighth, Ninth, and Tenth symphonies he premiered, and of Tchaikovsky. His recordings of the Tchaikovsky's last three symphonies, made in 1960 for Deutsche Grammophon while the orchestra was on tour in London, are touchstones of the Russian repertory.
