This is an excellent performance and resource.  These days, it can seem  that nothing less than an authentic performance will do, whether that necessitates playing Bach on 300 year old violins or Liszt being played by a full-blooded Hungarian.  And with the amount of recordings becoming available from countries with few previous U. S. releases, it can seem that only a Russian ensemble can truly perform Russian music.  Slavyanka's CD proves that philosophy to be false: an American choir can deliver an excellent account of Russian choral music.
