The quality of Rimsky-Korsakov's symphonies is the object of some disagreement, in particular with regards to the most famous of them, the second. I belong to those who view it as an utterly remarkable work, a truly original and compelling piece that doesn't really sound like anything else. The composer later re-published it as a symphonic suite, and although many seem to think that this categorization is more accurate, I myself find that it actually works quite well as a genuine symphony - but no matter; it is really a marvelous and memorable work. It is also far superior to the other two; no. 1 is very early and was revised several times over; it is a colorful work that the composer obviously struggled to make structurally coherent. Much the same is the case with no. 3, which contains a fine slow movement and a delightful 5/4 scherzo, but which doesn't overall leave a very lasting impression.
Kitajenko takes a bold and resolute approach. But in the end the performances aren't really a match for Järvi and the Gothenburg players - Rimsky-Korsakov was a master of orchestral colors, and these works need players who can realize these, and in that respect the rather coarse-grained and somewhat lifeless playing of the Bergen Philharmonic doesn't stand up to the lushness and textural atmospheres conjured up by Järvi and the Gothenburgers.
The same goes, in general, for the fillers. The famous Russian Easter Ouverture sounds a little gritty and lackluster, rather than ideally buoyant, colorful and ferocious. The performances aren't bad, but there are better versions available. Capriccio Espagnol fares better, but here the competition is even fiercer. The Sadko overture is, however, very fine, with lots of color and atmosphere (I do, by the way, urge readers to consider obtaining the whole fantasy fairy-tale opera). The piano concerto is far from a masterpiece, despite some decent tunes. Tozer plays it finely, but one could in the wish for some more flashy brilliance in the playing (Tozer seems to take it a little more seriously than its slight structure can bear).
All in all, this is a worthwhile set, but all the music is available in superior performances, so I would proceed with some care (Rimsky-Korsakov, whose main strength lies in conjuring up magic with orchestral colors, is one those composers who really requires as good performances as possible). Sound quality is rich and full, however.
