Shostakovich 3×3

And here is Bashmet/Muntian with the Viola Sonata.

From the Grove (in 'Posthumous reputation'):

Unlike that of many composers, Shostakovich's reputation with the musical public has grown steadily since his death, fuelled by post-glasnost' revelations about the society in which he lived. By most conceivable measurements, he has become the most popular composer of serious art music in the middle years of the 20th century.

[...] The doctrinaire rump of the Western avant garde never became reconciled to Shostakovich's importance, although some who started in that camp have at least come to recognize the multi-faceted complexity of his music. On the other hand, natural conservatives in Russia, Scandinavia, Britain and the United States acknowledged the influence but generally failed to grasp the underlying complexities of tone. Those complexities could only have taken the shape they did under the unique coercions of Stalin's Russia. As the most talented Soviet composer of his cursed generation Shostakovich was uniquely equipped to transcend those pressures, and as such his achievement is unrivalled.

Also, interesting is the summation in Prokofiev's entry:

A large number of the works that are free from political professions have a firm place in the international repertory, and he is rightly counted one of the major composers of the 20th century. He was not a great influence on younger generations of composers, unlike Schoenberg, Berg and Webern, Stravinsky, Bartók and Messiaen – except in the Soviet Union, where Soviet-trained musicians of a whole generation took their guidelines from either Shostakovich or Prokofiev, raising the achievement of one or the other to the status of a philosophy of life, and passed on their stylistic features to those who followed.
