This is a new release and both works are recorded in 2011 or so. If you wouldn't know this and got to know this disc say blindfolded you could easily think it's a mediocre recording done in the 1950s. Complete this with inadequate, under rehearsed, many times out of tune, insecure and wobbly string and wind playing and you know enough. The string pack of this orchestra is thin on sound and probably thin on players, not at all distinctive and semi-professional; they're recorded as if you hear some scratching over glass; they're to shy (or not supported by the conductor) to play their hearts out for what this music so much needs.
To be honest, Fibich is no Smetana and no Dvorak. He's an interesting second class composer so you've to play him as if he's in the Premier League, otherwise it won't appeal to you.
The symphony is a kind of Dvorak Symphony nr. zero and the filler Impressions from the Countryside is a kind of Czech suite. It's played rather slow so the contrast needed between the movements doesn't develop. Fibich, sometimes called the Czech Brahms, here sounds more like the Czech Raff. I really do admire Naxos likes to put these kind of composers to the fore, but this has to be done with more than 100% commitment otherwise it looses it's meaning. Go for the Detroit SO/Jarvi pack on Chandos and you've the three symphonies. Their shortcoming is the Americanized sound but you get a high ranking totally professional orchestral sound picture, a mass of strings and immaculate wind playing. (And the hints of Brahms will be recognized.)
