lusty cries of "Vivat!" that close the Polonaise. These revisions clearly went beyond mere reorchestration. He made substantial modifications to harmony, melody, dynamics, etc., even changing the order of scenes. Rimsky-Korsakov immediately came under fire from some critics for altering Boris, particularly in France, where his revision was introduced. The defense usually made by his supporters was that without his ministrations, Mussorgsky's opera would have faded from the repertory due to difficulty in appreciating his raw and uncompromising idiom. Therefore, Rimsky-Korsakov was justified in making improvements to keep the work alive and increase the public's awareness of Mussorgsky's melodic and dramatic genius. The Rimsky-Korsakov version remained the one usually performed in Russia, even after Mussorgsky's earthier original (1872) gained a place in Western opera houses. The Bolshoy Theatre has only recently embraced the composer's own version. Dmitriy Shostakovich (1940) Dmitriy Shostakovich worked on Boris Godunov in 1939–1940 on a commission from the Bolshoy Theatre for a new production of the opera. A conflation of the 1869 and 1872 versions had been published by Pavel Lamm and aroused keen interest in the piece. However, it did not erase doubts as to whether Mussorgsky's own orchestration was playable. The invasion of Russia by Nazi Germany prevented this production from taking place, and it was not until 1959 that Shostakovich's version of the score was premiered. To Shostakovich, Mussorgsky was successful with solo instrumental timbres in soft passages but did not fare as well with louder moments for the whole orchestra. Shostakovich explained: Shostakovich confined himself largely to reorchestrating the opera, and was more respectful of the composer's unique melodic and harmonic style. However, Shostakovich greatly increased the contributions of the woodwind and especially brass instruments to the score, a significant departure from the practice of Mussorgsky, who exercised great restraint in his instrumentation, preferring to utilize the individual qualities of these instruments for specific purposes. Shostakovich also aimed for a greater symphonic development, wanting the orchestra to do more than simply accompany the singers. Shostakovich remembered Alexander Glazunov telling him how Mussorgsky himself played scenes from Boris at the piano. Mussorgsky's renditions, according to Glazunov, were brilliant and powerful—qualities Shostakovich felt did not come through in the orchestration of much of Boris. Shostakovich, who had known the opera since his student days at the Saint Petersburg Conservatory, assumed that Mussorgsky's orchestral intentions were correct but that Mussorgsky simply could not realize them:
