One of the most popular and absorbing of Rimsky-Korsakov's operas, it is also one that requires a really good recording - one that captures all the colors and moods as well as the soaring arias and drama, without losing sight of the musical narrative. Not an easy thing, but at least Gergiev succeeds to a large extent. Sadko is based on one of the composer's relatively early tone poems, and is a true fairy tale opera that relies heavily on escapist magic and evocative atmospheres (with more than a dash of folk music and local color). The plot is somewhat confusing, and Rimsky admitted that the story itself wasn't the main issue; the characters are rather, shall we say, one-dimensional.
Despite the weaknesses of the storyline, Rimsky fills the opera with utterly magnificent music, and the beauty and power of many of the arias make one almost forget the shallowness of the characters who have them. It is really a sequence of the most lavishly detailed, gorgeously painted scenes; busy city markets with vendors of all nationalities, wonderful landscapes, journies under the sea, wistful dreaming and sorcery. And if you aren't really bothered by the lack of a coherent tale, you could hardly find much that is more dazzling, brilliant and engaging than Sadko. Not only is the orchestration at the level of Rimsky's best and the writing for voices superb, there is also a richness of truly imaginative themes and melodies, and if he didn't exactly have Verdi's sense of pacing, then - well, I cannot really care too much.
This is a live recording and the Kirov Orchestra acquits itself pretty well under Gergiev's leadership. There are some instances where the playing is less than ideally refined, but in general the colors and drama are there. Likewise, the choral contributions are generally excellent. The soloists, however, are a bit up and down. Best is Marianna Tarassova, who provide a beautiful rendition of Sadko's wife and who sings well in some of the most wonderful arias in the opera. But apart from her, things are more variable - without mentioning anyone in particular, there is much wobbling and missed pitch; I have heard most of the soloists on better form elsewhere, to be honest. Still, with the choral and orchestral contributions as good as this, and with fairly good sound (though the fact that it is live does challenge the balance on occasions), this is still an eminently recommendable version of this glorious opera, and probably the best available alternative.
